Description

This PR upgrades the BoxLang ORM module from Hibernate 5.6.15 to 7.4.8, which is a major version jump requiring significant architectural changes to the ORM integration layer.

Key Changes

Hibernate Version Upgrade

Updated hibernateVersion from 5.6.15.Final to 7.4.8.Final in gradle.properties
Updated Hibernate artifact coordinates from org.hibernate:* to org.hibernate.orm:* in build.gradle
Updated Jakarta EE imports: Changed from javax.persistence.* to jakarta.persistence.* across all converter classes

ORM Architecture Refactoring

Hibernate 6+ removed the tuplizer-based entity handling in favor of a representation strategy pattern. This required a complete redesign of how BoxLang entities are integrated:

Removed:

EntityTuplizer.java - The Hibernate 5 tuplizer implementation is no longer compatible with Hibernate 7

Added:

BoxRepresentationResolver.java - Implements ManagedTypeRepresentationResolver to route entity representation to BoxLang-aware strategies
BoxEntityRepresentationStrategy.java - Implements EntityRepresentationStrategy to provide instantiation, proxy, property access, and name resolution for BoxLang entities
BoxBootstrapContext.java - Wraps Hibernate's bootstrap context to inject the custom representation resolver
BoxRuntimeModelCreationContext.java - Wraps the runtime model creation context to use the custom bootstrap context
BoxPersisterFactory.java - Custom PersisterFactory service that injects the representation resolver into entity persisters
BoxPropertyAccess.java - Provides property getter/setter access for mapped properties

API Updates

BoxClassInstantiator: Updated to implement EntityInstantiator instead of Instantiator; refactored constructor to accept EntityRecord instead of EntityMetamodel
BoxProxyFactory: Updated to work with Hibernate 7's proxy model
BoxPropertyGetter/BoxPropertySetter: Updated to work with Hibernate 7's property access APIs
ORMApp.loadEntitiesByFilter(): Replaced deprecated Criteria API with HQL query builder
EntityLoadByExample.java: Replaced deprecated Criteria API with HQL-based filtering
EntitySave.java: Updated to use persist() and merge() instead of deprecated save()/saveOrUpdate()
ORMService.java: Updated to use SharedSessionContractImplementor instead of deprecated ClassMetadata
SessionFactoryBuilder.java: Removed EntityMode references (no longer applicable in Hibernate 7)
HibernateXMLWriter.java: Added formula element generation for computed properties
HQLQuery.java: Updated query option setters for Hibernate 7 API
ClassicPropertyMeta.java: Added cascade translation method to handle Hibernate 7 cascade syntax

Configuration Changes

Updated ORMConfig.java: Changed hibernate.temp.use_jdbc_metadata_defaults to hibernate.allow_metadata_on_boot with new enum values (allow/disallow)
Updated dialect mappings: MariaDB102Dialect → MariaDBDialect

Jira/Github Issues

This upgrade addresses compatibility with Hibernate 7.x and modernizes the ORM module to use current Jakarta EE standards.

Type of change

Breaking change (Hibernate 7 requires Java 11+ and Jakarta EE)
This change requires a documentation update

CI status: 10 known failures, migration in progress

The JUnit Report / tests (ubuntu-latest, JDK 21) checks are red on 623170c with 219 passed, 7 skipped, 10 failed. These are the expected in-progress state of the Hibernate 7 port, not regressions in unrelated code. They fall into three groups:

A. Test assertions still pinned to Hibernate 5 (4 tests). The version-string test expects 5.6.15.Final, and three ORMConfigTest cases assert the removed hibernate.temp.use_jdbc_metadata_defaults property, now replaced by hibernate.boot.allow_jdbc_metadata_access. Mechanical test updates.

B. Test code calling a removed API (2 tests). ORMGetSessionFactoryTest and EntitySaveTest use SessionFactory.getClassMetaData() / getDatabaseSnapshot() / findModified(), all removed in Hibernate 6. They need rewriting against the MappingMetamodel / EntityPersister.

C. Entity-typed HQL parameters (4 tests). Because BoxLang entities are dynamic maps, Hibernate 7 resolves an association parameter's Java type to java.util.Map and rejects both a raw primary key and an entity instance bound to it, where Hibernate 5 accepted them. This is a genuine gap in the dynamic-map representation port, tied to how detached entities present to Hibernate 7's stricter type layer.

Groups A and C, plus the two group-B rewrites, are held pending design decisions from the maintainer (detached-entity semantics, orm.xml timing, dialect policy). They will land together in the next push so CI does not burn a cycle on partial fixes. This PR is not ready to merge until then.

…cts, and datetime precision Phase 2 of the Hibernate 7.4 migration. bx-orm is the ORM abstraction, so these keep the BoxLang-facing behavior identical while hiding Hibernate 7's breaking changes. - HQLQuery: resolve association parameters (a primary key or an entity instance) to the managed entity before binding, using the SQM parameters' anticipated types. Restores Hibernate 5's lenient parameter handling that Hibernate 7's strict validation rejected. - ORMApp.resolveEntityReference(): shared helper that turns a key or entity into the managed reference Hibernate expects. - EntitySave: detached entities are re-attached via merge() and the managed state is copied back into the caller's instance, so entitySave() still leaves the passed object live with its generated id and event changes (Hibernate 7 removed saveOrUpdate()). - DateTimeConverter maps to java.sql.Timestamp so Hibernate 7 binds fractional seconds instead of truncating date/time properties to whole seconds. - ORMConfig: dialect aliases (including legacy version-specific names) resolve to Hibernate 7 base dialects, in core or hibernate-community-dialects, with a one-time deprecation warning; replaces the removed hibernate.temp.use_jdbc_metadata_defaults with hibernate.boot.allow_jdbc_metadata_access. - Tests: updated version, metadata-on-boot, and dialect assertions; rewrote the getClassMetaData metadata/dirty-check tests onto getMappingMetamodel().getEntityDescriptor().

Add standalone boot + CRUD smoke tests broadening dialect coverage beyond MySQL and SQLite: - DerbyDialectBootTest runs everywhere via embedded, in-memory Derby. - PostgreSQLDialectBootTest and MariaDBDialectBootTest are gated on the ORM_TEST_POSTGRES / ORM_TEST_MARIADB env vars so they skip locally and run in CI against service containers. Each test boots its own isolated BoxLang app (raw JDBC connectionString datasource, dbcreate=dropcreate) and asserts an entity can be saved and queried back. build.gradle now pulls the Derby, PostgreSQL, and MariaDB JDBC drivers as test dependencies and copies them into the module's isolated classloader dir; the CI workflow adds Postgres and MariaDB service containers.

src/main/java/ortus/boxlang/modules/orm/HQLQuery.java:391

List parameters are expanded by incrementing parameterIndex, but entityParams is keyed by the original SQM parameter position. Consequently, for an association query such as WHERE manufacturer IN (:ids) with two primary keys, only the first list element is resolved through resolveBindValue; subsequent elements are bound as raw scalars and Hibernate 7 rejects the entity-typed parameter. Capture the association entity name before expanding the list and resolve every element with that same target.

			int parameterIndex = 1;
			for ( QueryParameter param : this.parameters ) {
				if ( param.isListParam() ) {
					Array list = ( Array ) param.getValue();
					for ( Object value : list ) {
						hqlQuery.setParameter( parameterIndex, resolveBindValue( parameterIndex, value, entityParams ) );
						parameterIndex++;

This replacement map omits legacy aliases that were accepted by the Hibernate 5 switch, including FRONTBASE, INTERBASE, JDATASTORE, MCKOI, POINTBASE, and PROGRESS. Because unknown short names are returned unchanged, applications using any of these settings now pass an unresolved alias to Hibernate 7 and fail during boot; retain a compatibility mapping for every previously supported alias.

The resolver fallback is hard-wired to org.hibernate.metamodel.internal.ManagedTypeRepresentationResolverStandard, an internal Hibernate implementation. This contradicts the public-SPI boundary described for the Hibernate 7 integration and can break linkage on a Hibernate 7.x update; isolate the version-specific adapter or use a supported public resolver contract.

import org.hibernate.metamodel.internal.ManagedTypeRepresentationResolverStandard;

src/test/java/ortus/boxlang/modules/orm/hibernate/converters/DateTimeConverterTest.java:39

This test uses a whole-second LocalDateTime and only checks non-null, so it cannot detect the sub-second precision regression that this converter change is intended to fix. Use a value with non-zero fractional seconds and assert the converted timestamp equals the original instant.

Add a JMH microbenchmark suite (src/jmh) measuring entity CRUD and HQL throughput against an embedded Derby datasource: - `./gradlew jmh` benchmarks the current build (Hibernate 7). - `./gradlew jmhCompare` benchmarks Hibernate 7 (current) against the last Hibernate 5 release (module 1.7.0, downloaded and set up automatically), runs each version in its own forked JVM, and prints a side-by-side table. The benchmark loads the ORM module (and thus Hibernate) from a swappable module path, keeping only BoxLang + JMH on the outer classpath so Hibernate resolves inside the module's isolated classloader - mirroring production and keeping the version comparison honest. Rigor is overridable via -PperfForks / -PperfWarmup / -PperfIterations. See src/jmh/README.md.

Copilot review addressed

Fixed and pushed (commits 398fcb9, 85d7d6d):

HQL injection (critical) — the entityLoad order by property is now validated and canonicalized against the entity's persistent properties before it is interpolated into the HQL.
Association filter values — entityLoad filter queries resolve a to-one association value (a primary key or entity instance) to a managed reference before binding, matching ormExecuteQuery().
ormExecuteQuery IN (:list) of association values — every expanded list element is now resolved against the list's association target, not just the first element.
entityLoadByExample — predicates are built from the inheritance-aware persistent property set and now exclude ids, the version, and associations.
entitySave — after merge(), both the this and variables scopes are synced back onto the caller's instance so generated ids / event-updated values are not left stale.
BoxPropertyGetter.getMember() — stale Javadoc removed.

Not changing:

Legacy dialect aliases (FrontBase, Interbase, JDataStore, McKoi, PointBase, Progress) — these dialects were removed from Hibernate in 6+ and have no equivalent in Hibernate 7 (neither core nor hibernate-community-dialects). There is no class to map them to, so an unresolved pass-through that fails clearly at boot is the honest behavior; a bogus mapping would fail the same way with a more confusing error.
BoxRepresentationResolver embeddable fallback to the internal ManagedTypeRepresentationResolverStandard — under review with the maintainer; options are being weighed for whether a public alternative exists.

Local suite: 238/239 pass; the single failure is the known local-MariaDB fractional-seconds quirk that passes on CI (MySQL 8).

Per review feedback, clarify BoxRepresentationResolver's embeddable branch: it delegates composite ids / components to Hibernate's built-in ManagedTypeRepresentationResolverStandard.INSTANCE because Hibernate exposes no public factory for the default embeddable strategy. Document it as the single, guarded internal touch-point in both the class javadoc and AGENTS.md, so it's the one place to revisit if a future Hibernate release relocates it. No behavior change.

Add two CPU-focused benchmarks to complement the I/O-bound CRUD benchmark: - ORMReadBenchmark: bulk hydration of N rows (default 2000) into BoxLang entities, exercising per-entity/per-property work at volume. - ORMBootBenchmark: cold ORM application boot (entity discovery + mapping generation + SessionFactory build), SingleShotTime, run one boot per fork. Adds a richer Widget entity (varied typed properties) to the derbyApp fixture so the read path exercises the attribute converters. README documents how to run each and how to read the sampling profiler.

…#100) Add a MappingXMLWriter that emits Hibernate 7's modern <entity-mappings> format as an alternative to the legacy hbm.xml DTD writer, for Hibernate 8 readiness. Opt in per app via the ormXmlMapping ORM setting (default false), so production and all existing tests stay on the HBM writer with zero behavior change. Covers: dynamic (MAP) entities as <entity metadata-complete="true">, ids with the increment generator, JPA AttributeConverters (<convert>), <version>, discriminators, single-table inheritance (incl. per-subclass secondary table) and joined inheritance, many-to-one/one-to-one, one-to-many/many-to-many, composite ids, formulas, and second-level cache. A Derby smoke test (DerbyOrmXmlMappingBootTest) boots an app with the flag on and round-trips these constructs. Known Hibernate 7.4.8 limitation for class-less dynamic entities: uuid id generation and byte[] basic attributes are not expressible in the modern format (documented with TODOs). These are resolved by moving entities to real POJO facades, a separate follow-up. Full suite: 242 completed, 1 failed (the known local-MariaDB fractional-seconds quirk that passes on CI MySQL 8), 9 skipped. No HBM regression.

…e 1) First slice of the composition-based POJO representation. EntityFacadeFactory generates, per entity at runtime (ByteBuddy), a real Java "facade" class that Hibernate maps as a normal POJO. The facade holds no state: each generated getter/setter delegates to a BoxEntityState, backed in production by the entity's BoxLang instance (which is a Map), so the BoxLang class and the facade share one state store. Because the facade is a real class with a real, typed id member, Hibernate's id-generator resolution works - including uuid, which is impossible for class-less dynamic (MAP) entities. A test proves a generated facade maps with a uuid id and persists correctly, delegating through the backing state. Not yet wired into the representation strategy (that is stage 2); nothing calls the factory yet, so existing behavior is unchanged. Adds an explicit byte-buddy dependency (pinned to Hibernate's version).

…(stage 2) Wire the generated entity facades (stage 1) end to end, gated on a new default-OFF `entityFacades` ORM setting. When enabled, entities map to real POJO facade classes and Hibernate does real id generation (uuid works); when off, the representation is byte-for-byte the original dynamic MAP behavior. - ORMConfig/ORMKeys: add `entityFacades` (default false). - facade.BoxIClassRunnableState: BoxEntityState over an IClassRunnable, writing both this + variables scopes (mirrors BoxPropertySetter); exposes getRunnable(). - facade.EntityFacadeNaming / FacadeSupport: deterministic facade FQN + id Java type, and the wrap/unwrap boundary with per-instance memoization (hidden $bxORMFacade key, since an IClassRunnable's hashCode is content-based). - BoxFacadeInstantiator: POJO-mode instantiator building the IClassRunnable via BoxClassInstantiator then wrapping it in the facade. - BoxEntityRepresentationStrategy/BoxRepresentationResolver/BoxPersisterFactory: facade branch (POJO mode, facade JavaType, standard property access, lazy off); MAP branch unchanged. - SessionFactoryBuilder: generate one facade per entity into the module loader before boot. HibernateXMLWriter: emit <class name=facadeFQN entity-name=...> in facade mode. - BIF/boundary unwrap (ORMService.getEntityName, EntityNew/EntitySave, ORMApp read paths, HQLQuery, EventListener) so devs only ever get the BoxLang class and events fire on it. FacadeRepresentationBootTest: boots facade-mode Derby and round-trips a uuid-keyed entity through entityNew/save/loadByPK/ormExecuteQuery. Full suite flag-off: 244 completed, 1 failed (known local-MariaDB fractional-seconds quirk), 9 skipped. No MAP regression. Associations, composite ids, and lazy proxies in facade mode are follow-ups.

Bring facade (POJO) mode to parity with MAP mode for associations and lazy loading; still gated on entityFacades, MAP mode untouched. - Association accessors translate at the Hibernate/BoxLang boundary: a to-one getter wraps the scope's IClassRunnable to the target facade for Hibernate, its setter unwraps back; a to-many accessor hands Hibernate its managed collection of facades and stores a FacadeCollectionView (a live List that unwraps facades->IClassRunnable on read, wraps on write) in the scope. Devs navigating parent.getChild()/getChildren() only ever see BoxLang instances. - EntityFacadeFactory: PropertySpec gains AssocKind (NONE/TO_ONE/TO_MANY); to-many accessors declared List<Object> for Hibernate 7 element typing. SessionFactoryBuilder tags each association property's kind. - Lazy proxies re-enabled for facades: representation strategy provides BoxProxyFactory + BoxProxy proxy type; HibernateXMLWriter no longer forces lazy=false; BoxLazyInitializer unwraps the loaded facade to the IClassRunnable (no-op in MAP mode). A lazy to-one arrives as a BoxProxy that initializes on access and yields the BoxLang instance. - FacadePropertyAccess: wraps standard reflection access to coerce a raw IClassRunnable owner to its facade (Hibernate hands the id-getter the raw instance during FK/isTransient breakdown). BoxIClassRunnableState.get() reads the variables scope (aligns with MAP-mode BoxPropertyGetter). FacadeAssociationBootTest (Derby, real BIFs): a uuid-keyed one-to-many + many-to-one graph and a lazy to-one round-trip, navigation yields IClassRunnable (never facades). Full suite flag-off: 246 completed, 1 failed (known local-MariaDB fractional-seconds quirk), 9 skipped. No MAP regression. Composite ids and inheritance in facade mode remain follow-ups.

…e 2c) Close the last parity gaps between facade (POJO) mode and MAP mode. - EntityFacadeFactory: multi-id facade generation plus subclass facades that extend their parent facade (rely on ByteBuddy's imitated ctor to avoid duplicate-signature failures). - SessionFactoryBuilder: generate facades ordered by inheritance depth (roots first); no longer require exactly one id per entity; subclasses receive the parent facade as their generated superclass. - HibernateXMLWriter: emit name= on <subclass>/<joined-subclass> and on composite-id markup in facade mode. - ORMApp: load-by-id builds a facade id instance carrying the struct key values for facade-mode composite ids; MAP-mode Map branch untouched. - Tests: FacadeCompositeIdBootTest, FacadeInheritanceBootTest and their fixture apps (facadeCompositeApp, facadeInheritanceApp). Facade mode is now at parity with MAP mode for simple ids, uuid, associations, lazy proxies, composite ids, and single-table/joined inheritance. All flag-gated behind entityFacades; zero MAP regression. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SnmFsqBfa9SR4V1rRXw57X

… app Stage 3 (prove): flip the default entity representation to POJO facades (entityFacades defaults to true) so the whole suite exercises facade mode, and fix the one real defect that flipping the default surfaces. Cross-app facade collision: facade class names and the wrap/unwrap registry were keyed by bare entity name. Once every application generates facades, two apps in one JVM that each map a same-named entity (e.g. User, Animal) to a different shape collided on one global facade class / registry entry, handing one app another app's facade (wrong id/property types). Fix: namespace facades per application. - ORMConfig.facadeNamespace, stamped at ORMApp startup from the (unique) application name via EntityFacadeNaming.sanitizeNamespace. - EntityFacadeNaming.facadeClassName(namespace, entityName) -> per-app FQN (...generated.<namespace>.<Name>Facade); plus sanitizeNamespace/namespaceOf. - FacadeSupport registry keyed by namespace|entityName; instances stamped with their owning namespace so wrapInstance resolves the right facade even before it is memoized. BoxFacadeInstantiator stamps the namespace. - HibernateXMLWriter and SessionFactoryBuilder pass the namespace through facade generation, registration, and the <class name=...> emitted for Hibernate. The modern mapping.xml writer does not yet support facades (planned), so the derbyOrmXmlApp fixture is pinned to entityFacades=false to keep validating that writer in MAP mode. MAP mode remains fully available via the flag. All facade + Derby smoke tests pass locally (facade simple/uuid, associations, lazy proxies, composite ids, inheritance; Derby dialect; mapping.xml in MAP mode). The MySQL-backed suite runs on CI.

Flipping facades to the default surfaced BIF paths that still handed Hibernate the raw IClassRunnable (which it no longer tracks - it tracks the facade) or handed developers a raw facade. Complete the boundary: - EntityReload: refresh the managed facade, not the detached IClassRunnable. - EntityIsAttached: check containment of the facade. - EntityLoadByExample: unwrap facade results to BoxLang instances. - BoxClassInstantiator: the generated to-many helpers (hasX/addX/removeX) now operate on the scope collection as a List<Object>, so a facade-mode FacadeCollectionView works alongside a MAP-mode Array/PersistentBag. - ORMApp.resolveEntityReference: a primary key or entity bound as an association query parameter resolves to the managed facade (session.get) rather than a lazy BoxProxy, so Hibernate 7's parameter type check accepts it. Added FacadeSupport.managed() helper for the session-op boundary. - HibernateXMLWriter: guard the facade branch against a null entity name. Tests: - HibernateXMLWriterTest pins itself to MAP mode (it asserts HBM structural output, which is representation-agnostic; facade naming is covered by the boot tests). - ORMClearSessionTest probes attachment via entityIsAttached (the supported, facade-aware BIF) instead of a raw session.contains of a BoxLang instance. - FacadeAssociationBootTest gains Derby coverage for reload, isAttached, to-many add/has, entityLoadByExample, and a PK-as-query-parameter bind.

…fire The last two facade-mode CI failures, both surfaced by making facades the default representation. 1. removeX during iteration (EntityLoadByPKTest.testEntityRemoveMethod): getChildren().each( c => parent.removeChild( c ) ) dropped/nulled elements. The scope holds a live FacadeCollectionView over Hibernate's managed collection; BoxLang's .each iterates by index (Array.intStream + size()>idx?get(idx):null), so removeX shrinking the collection shifts indices under the iterator. BoxLang's native Array is copy-friendly, which is why MAP mode works. Fix: BoxClassInstantiator now installs a facade-mode to-many getter that returns a stable snapshot Array (a copy of the current IClassRunnable elements) while addX/removeX keep mutating the live view - so iteration is stable and structural changes still flow to Hibernate. In MAP mode the scope already holds a plain Array, returned as-is. 2. Duplicate preUpdate/postUpdate (EntityEventsTest.testEntityUpdateEvents): updating an entity with an association/collection fired its update events twice. EventListener's preUpdate/preInsert state-sync wrote every scope property value back into Hibernate's event state array; for association and collection slots the facade's FacadeCollectionView/facade reference differs from Hibernate's own state entry, so overwriting it corrupted Hibernate's collection tracking and triggered a spurious second UPDATE. The sync now skips association and collection property types (event handlers change basic values, not associations; MAP mode never overwrote these either since the scope held Hibernate's own instance). Both reproduced and validated on embedded Derby via new FacadeAssociationBootTest cases (remove-during-each, single-element remove, and update-events-fire-once on a collection-bearing entity); the Manufacturer fixture gains an event log.

…keys The final facade-mode CI failure (EntityLoadByPKTest.testEntityRemoveMethod): removeX on a to-many silently removed nothing when the element's id property was named differently from the owning entity's. getRemoveMethod matched collection elements using the OWNER instantiator's identifier keys (this.identifierKeys) against the elements' scopes - so for an owner keyed `id` holding elements keyed `vin` (the app's Manufacturer -> Vehicle), the key was never present on the element and the filter matched nothing. The facadeApp fixtures masked this because owner and element both used `id`. Fix: remove the element the developer passed by identity/equality (it comes from iterating the same association), independent of id property names. The FacadeCollectionView unwraps facades on compare, so an IClassRunnable argument still matches its managed facade in the backing collection. Applies to MAP mode too (a plain Array/PersistentBag of IClassRunnables). Validated on Derby with a new Fleet(id=fleetId) -> Truck(id=plate) fixture whose id names deliberately differ (and from the owner's), reproducing the app's shape.

Make the Hibernate 7 mapping.xml writer work with the default facade representation, closing the gap that pinned `ormXmlMapping` apps to MAP mode. - MappingXMLWriter emits the generated facade `class` on `<entity>` and the facade FQN as association `target-entity` in facade mode; MAP mode still emits class-less `metadata-complete` entities. - The modern format binds the mapped class via the JPA annotation path, so a facade entity's Hibernate entity-name is its facade class FQN. Route by-name Session/metamodel calls through the JPA import name (ORMApp.hibernateEntityName via getImportedName) and make BoxEntityNameResolver report the facade FQN for BoxEntityFacade instances, so assertInstanceOfEntityType and by-name lookups resolve. - BoxRepresentationResolver keeps a facade-FQN fallback index so strategy resolution succeeds when Hibernate reports the entity-name as the facade class. - Flip the derbyOrmXmlApp fixture to facade mode; regenerate its mapping XML. Verified locally on Derby: DerbyOrmXmlMappingBootTest (mapping.xml facade) and FacadeAssociationBootTest (hbm facade) both green. Remaining suite failures are only the local MySQL container being unavailable.

@uuidgenerator

Flip the module to always emit Hibernate 7's modern mapping.xml format and remove the legacy hbm.xml DTD writer and the ormXmlMapping opt-in flag. hbm.xml is deprecated-for-removal in Hibernate; BoxLang-facing ORM behavior is unchanged. - MappingGenerator/SessionFactoryBuilder always use MappingXMLWriter and the combined <entity-mappings> file; the .orm.xml extension is the only output. - Remove HibernateXMLWriter + HibernateXMLWriterTest, the ormXmlMapping ORMConfig field and ORMKeys entry. Relocate the shared escapeReservedWords/toHibernateType helpers onto MappingXMLWriter. Delete stale .hbm.xml fixtures; regenerate .orm.xml. - All test apps now run facade + mapping.xml (the previous default was facade + hbm). Fixes surfaced by the switch: - BoxFacadeInstantiator.isInstance now recognizes a facade by its real class, so a primary-key load (entityLoadByPK/session.get/byId) of an entity managed in the current session no longer returns null. The old name comparison rejected the managed facade because the modern format's entity-name is the facade class FQN, not the BoxLang name. Real-class matching also fixes subclass polymorphism. - The writer emits the legacy string uuid generator for facade entities instead of @uuidgenerator, whose java.util.UUID JDBC binding missed the VARCHAR id column on a session.get/byId load (HQL matched, PK load did not). Verified locally on Derby: FacadeRepresentation/Inheritance/Association/CompositeId, DerbyOrmXmlMapping, and DerbyDialect boot tests all green. Full MySQL suite runs in CI.

…ribute name Facade mode + modern mapping.xml: a bidirectional association whose owning property name is capitalized (e.g. a many-to-one named `Client`) broke SessionFactory boot for the whole application with: AnnotationException: Collection '...ClientFacade.contacts' is 'mappedBy' a property named 'Client' which does not exist in the target entity 'ClientContactFacade' Hibernate discovers a facade entity's attributes by JavaBean introspection of its generated getX/setX accessors, which decapitalizes the leading character (`Client` -> `client`). A collection's mapped-by must therefore name that decapitalized attribute, not the original BoxLang property name. The writer now runs mapped-by through Introspector.decapitalize in facade mode (MAP mode is class-less and keeps the XML name verbatim). This was the single root cause of all 31 MariaDB CI failures on the previous commit (the main app's ClientContact.Client many-to-one). Adds FacadeMappedByBootTest + facadeMappedByApp, a minimal Derby fixture whose Item.Owner many-to-one reproduces the exact failure and round-trips the graph.

…ping The modern mapping.xml writer skipped binary (byte[]) properties, but the facade class still generated a getX()/setX() accessor for them. Hibernate then auto-discovered that Object-typed accessor and mapped the column as JAVA_OBJECT (SqlTypes 2000), which has no SQL type name -> schema export and multi-table joined-inheritance strategy setup failed. This broke SessionFactory boot for the whole app (e.g. the main test app's Employee extends User graph with an `avatar` byte[] column), the second root cause of the MariaDB CI failures. Fix (facade mode, where the entity is a real class): - SessionFactoryBuilder generates a concrete byte[] accessor for a binary property (not Object), so Hibernate infers the column's SQL type from it. - MappingXMLWriter emits a plain <basic> (column only, no converter/java-type) for a binary property, letting Hibernate resolve VARBINARY/BLOB from the byte[] accessor. Binary stays skipped only in class-less MAP mode, where byte[] is not expressible in the modern format. FacadeMappedByBootTest now also persists and reads back a byte[] photo column.

An inverse one-to-many that declares no explicit fkcolumn (the FK is defined only on the inverse many-to-one, e.g. the main app's Author.rejections -> Rejection.user) produced no mapped-by, so Hibernate treated the collection as owning and synthesized a default join table. That join table's FK to the owning table (users) then failed schema export, and the owning entity's tests all failed at runtime with "Table 'test.users' doesn't exist" - the shared cause of the remaining MariaDB failures. resolveMappedBy now falls back, when the collection has no key column, to the target entity's back-reference to-one (matched by entity type) to derive mapped-by, so the collection stays non-owning and no join table is synthesized. FacadeMappedByBootTest's Owner.items now declares no fkcolumn to exercise this path.

The modern mapping.xml writer emitted a text/clob property as an in-row varchar(length) (e.g. varchar(8000)). A wide varchar counts toward a table's maximum row size; the main app's Author (table `users`) has two text length="8000" columns, whose varchar(8000) pushed the table past MySQL 8's 65535-byte row limit, so CREATE TABLE failed and every test touching that entity failed at runtime with "Table 'test.users' doesn't exist". MariaDB tolerated the wide varchar, which is why local Derby/MariaDB runs passed while MySQL CI did not. The writer now emits <lob/> for a text/clob property and drops the column length, so Hibernate creates a TEXT/LONGTEXT (large-object, off-row) column - both semantically correct and immune to the row-size limit. Reproduced and verified against MySQL 8 (the CI database) with the full app/ ContentBox suite: the previously-unbootable app now boots and 205/215 tests pass (the remaining 10 are unrelated behavioral issues, addressed separately). Also broadened FacadeMappedByBootTest (mapped-superclass parent, a text/lob column, and an inverse one-to-many with no fkcolumn) to guard these on Derby.

…acade In facade (POJO) mode Hibernate manages the generated facade, not the caller's IClassRunnable, and by-name cache/metamodel calls key off the facade class (the modern mapping.xml entity-name), not the BoxLang name. Three BIFs missed this and failed on MySQL with "Unknown entity type" / "Non-entity object instance passed to evict": - entityDelete: wrap to the facade and remove it (re-associating a detached facade via merge first, since Hibernate 6+ rejects removing an unmanaged instance). - entityMerge: wrap to the facade, merge by Hibernate entity-name, and return the caller's BoxLang instance (unwrapped from the managed facade). - ormEvictEntity: evict the L2 cache under ORMApp.hibernateEntityName (the facade class), keeping the BoxLang name only for id-type resolution. Verified against MySQL 8 (the CI database) with the app/ suite: previously-failing delete/merge/evict and the event-driven delete now pass (10 -> 8 failures); the remaining 8 are separate issues addressed next.

In facade (POJO) mode Hibernate manages a generated facade and the modern mapping.xml entity-name is the facade class FQN, so code reaching through the raw ormGetSession()/ormGetSessionFactory() to call Hibernate with a BoxLang entity name or instance failed (Unknown entity type / Non-entity object passed to evict). The ORM BIFs translate at that boundary, but consumers such as cborm use the raw Session/SessionFactory directly. Add FacadeAwareHibernate: a dynamic proxy over the target's full interface set (so SPI casts like SessionFactoryImplementor still work) that, per call, rewrites a registered BoxLang entity name to its Hibernate entity-name (via getImportedName; non-entity strings such as HQL/property names pass through), wraps IClassRunnable arguments to their managed facade, and unwraps facade results / re-wraps returned Session/SessionFactory/Cache/Metamodel so chained calls keep translating. Applied only in facade mode (MAP mode's entity-name is already the BoxLang name). Verified against MySQL 8 (CI database): entityMerge (session.detach), ormEvictEntity (getCache().containsEntity), ormGetSessionFactory and entitySave dirty-state (getMappingMetamodel().getEntityDescriptor) by BoxLang name now pass; full app/ suite 8 -> 3 failures with no regressions.

…ables A discriminated single-table subclass that maps its own columns to a separate join table is emitted as a JPA <secondary-table>. Unlike the @SecondaryRow annotation (owned defaults to true), Hibernate's orm.xml binding leaves a <secondary-table> read-only when owned is omitted: the row is SELECTed via outer join but never written. That silently dropped the subclass's own columns and FKs on insert (e.g. ClientContact.Client persisted as null) and skipped the secondary-row delete (FK violation on cascade). Emitting owned="true" makes Hibernate manage the secondary table's insert/update/delete, the modern-format equivalent of the classic hbm <join> Hibernate manages by default. Also fixes MappingGeneratorTest to check the regenerated .orm.xml file (the module now emits mapping.xml, not hbm.xml). Reproduced and verified against MySQL 8 with the app/ ClientContact and cbContentStore entities; isolated the cause with standalone plain-Hibernate tests (annotations write the secondary row; orm.xml does not unless owned).

Adds a HibernateFeatureCoverageBootTest (Derby, facade/default mode) that round-trips a <version> optimistic-lock column and a computed formula property. Building it surfaced three facade-mode regressions, all fixed: - ClassicPropertyMeta rejected the normalized ormType "integer" for a version (only accepted int/long/short) and omitted timestamp versions. - The facade generated an Object accessor for the version property, which is not a legal Hibernate version type and failed SessionFactory build; it now generates a concrete numeric/temporal accessor. - The preInsert/preUpdate event state-sync overwrote Hibernate's managed version slot with the scope's stale value, causing OptimisticLockException; it now skips the version slot as it already skips associations/collections. First installment of the documented-feature coverage sweep. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SnmFsqBfa9SR4V1rRXw57X

…-collection> A fieldtype="collection" value collection (a collection of scalars) was silently dropped: COLLECTION was neither a column, association, nor version, and the code held only a dead "not yet supported" note. It is now parsed as a collection, categorized as an association, and emitted as a JPA <element-collection> (BAG) with the element value declared as <column> + an explicit Hibernate JavaType descriptor (<java-type>) — <column> and <convert> are mutually exclusive in the element-collection schema. The facade exposes it as a to-many List whose scalar elements pass through unwrapped. HibernateFeatureCoverageBootTest round-trips an array-of-strings element collection on Derby (facade/default mode). Map collections are next.

Adds a TO_MANY_MAP facade AssocKind with a Map accessor; the interceptor converts the BoxLang Struct's Key keys to their scalar form when handing the map to Hibernate (and leaves Hibernate's own map untouched).
