Hibernate 7 - Step 2 - #15568

Hibernate 7.4 Breaking Changes (Application Migration)

These are the Hibernate 7.4 behaviours that differ from Hibernate 5.6 and remain the application owner's responsibility when migrating from the Hibernate 5 plugin to Hibernate 7. GORM-facing issues that this PR already resolves are intentionally omitted - only the breaking changes that survive are listed.

Status	Area	Hibernate 5.6 behavior	Hibernate 7.4 behavior	What can break in applications	Application migration action
Remaining app migration item	Hibernate module dependencies	Applications commonly depend on Hibernate 5 aligned Grails artifacts and constraints.	Applications must resolve the Hibernate 7 aligned artifacts and constraints together.	Mixing `grails-data-hibernate5`, H5 BOM constraints, or H5-only transitive dependencies with the H7 runtime can fail dependency resolution or application boot.	Use the Hibernate 7 BOM/artifacts consistently. Do not mix H5 and H7 GORM/Hibernate artifacts in the same application runtime.
Remaining app migration item	H5-specific cache setup	H5 applications may rely on Ehcache/Hibernate 5 cache integration and related configuration.	H7 no longer supports the same H5-specific cache integration path.	Boot can fail before application code runs when H5 cache classes or region-factory settings are still configured.	Remove H5-specific cache dependencies and configuration. Reintroduce caching only with H7-compatible cache providers and settings.
Intentional behavior change	Property-map query keys	H5-era code could accidentally rely on permissive interpolation of property-map keys.	The H7 path validates keys against real domain properties before generating HQL.	Code that passes computed, misspelled, or HQL-fragment-like keys to `findWhere` or `findAllWhere` now fails fast.	Pass only real domain property names as map keys. Move dynamic predicates to criteria, where queries, or explicit HQL with bound parameters.
Documented behavior change	Locking and query cache	H5-era code may combine cacheable query settings with lock settings.	H7 locked queries are not query-cacheable; this PR disables query caching when `lock: true` is used.	Code expecting a locked query to use the query cache will behave differently.	Do not rely on query cache for pessimistically locked queries. Treat locked queries as database reads requiring fresh row state.
Remaining app migration item	Read-only entity collections	H5 could allow collection mutation even when the owning entity was loaded read-only.	H7.3 and later mark collections owned by read-only entities as read-only too.	Mutating a collection on a read-only entity can now fail.	Reload the entity in a writable session before changing its collections. Do not mutate associations on read-only entities.
Remaining app migration item	Timeout exception type	H5 and earlier H7 lines commonly exposed `QueryTimeoutException` or `LockTimeoutException` for query and lock timeout paths.	H7.3 and later may throw `PersistenceException` when the database marks the transaction for rollback.	Timeout handling that catches only the narrower exception types can miss rollback-producing timeout failures.	Catch `PersistenceException` around direct Hibernate/JPA timeout-sensitive code and inspect the cause when necessary.
Remaining app migration item	Native SQL temporal values	H5 native queries commonly returned `java.sql` temporal values.	Hibernate 7 native SQL queries return `java.time` temporal values by default.	Native SQL result handling can fail if it casts to `java.sql.Date`, `Time`, or `Timestamp`.	Update result handling to `java.time` types, or set `hibernate.query.native.prefer_jdbc_datetime_types=true` during migration.
Remaining app migration item	Version-column DDL	H5 schema export did not necessarily declare version columns `not null` by default.	H7.3 declares `@Version` columns `not null` by default.	Schema validation or generated migration diffs can show new not-null constraints on version columns.	Validate generated DDL against existing schemas before using `dbCreate=update`, especially for legacy nullable version columns.
Remaining app migration item	General DDL generation	H5 generated different column definitions for several mappings.	H7 changes generated DDL for mappings including `char`/`Character`, Oracle floating point, `@ElementCollection` sets, `@CreationTimestamp`, `@UpdateTimestamp`, and Oracle 23c LOB columns.	Automatic schema update can propose or apply unexpected column, constraint, or LOB storage changes.	Prefer explicit database migrations for production schemas. Compare generated DDL in staging before using schema update tooling.
Remaining app migration item	Schema actions and `import.sql`	Schema actions could be skipped when no entities were mapped.	H7.3 and later process schema actions even when no entities are mapped.	An accidental `import.sql` on the classpath can run where it was previously ignored.	Remove accidental `import.sql` files from the runtime classpath or make schema-generation settings explicit.
Remaining app migration item	MySQL default fetch depth	H5 and earlier Hibernate lines could apply a MySQL dialect-level `hibernate.max_fetch_depth=2` default.	H7.4 removes that MySQL-specific default.	Applications relying on the implicit MySQL fetch depth can see different association fetch plans.	Set `hibernate.max_fetch_depth` explicitly if the application relies on that behavior.
Remaining app migration item	Fetch joins with limits	H5 commonly handled collection fetch-join limits in memory.	H7.4 applies pagination or limits with collection fetch joins in SQL.	Queries combining `max`/`offset` or limits with collection fetch joins can return a different row/window shape.	Review those queries and set the `org.hibernate.limitInMemory` query hint only when the previous in-memory behavior is required.
Remaining app migration item	Oracle HQL date expressions	Oracle `current date` and `local date` could preserve a time component because Oracle has no true date-only function.	H7.4 translates them to `trunc(current_date)`.	Oracle HQL predicates depending on the time part can behave differently.	Review Oracle queries that use `current date` or `local date` and change the expression if a timestamp is required.
Remaining app migration item	Eager `@Any` mappings	Eager `@Any` mappings were loaded by a separate select.	H7.4 join-fetches eager `@Any` associations when loading an entity by id.	Direct Hibernate `@Any` mappings can produce different SQL shape and row width.	Review direct Hibernate `@Any` mappings for performance and row duplication implications.
Remaining app migration item	Spanner PostgreSQL dialect	Spanner PostgreSQL dialect lived in `hibernate-community-dialects` under `org.hibernate.community.dialect`.	H7.4 moves it into `hibernate-core` under `org.hibernate.dialect`.	Explicit dialect configuration can reference a class that is no longer correct.	Use `org.hibernate.dialect.SpannerPostgreSQLDialect` or rely on automatic dialect resolution.
Remaining app migration item	Envers `NOT_AUDITED` associations	H5-era Envers behavior could read the associated target from its audit table even when `NOT_AUDITED` was requested.	H7.3 respects `RelationTargetAuditMode.NOT_AUDITED`.	Historic audit reads can return the current associated entity instead of a historic row.	Verify Envers audit queries that use `RelationTargetAuditMode.NOT_AUDITED`.
Remaining app migration item	Programmatic datastore package scanning	H5 test/application setups may accidentally scan a package that still found needed classes.	H7 tests exposed that the datastore must scan the package containing the actual support domains/services.	Programmatic `HibernateDatastore` setup can miss domain or service classes if the scanned package is wrong.	When constructing datastores manually, pass the package that contains the domain/service classes, not merely the spec or caller package.

Reopening. This PR replaces #15530

Please note that I split off a prerequisite PR #15654

This allows us to better see what changed between hibernate 5 & 7 - otherwise the hibernate 7 code looks like it was just added instead of changed. Commit a47d8cb is the original commit prior to this split if we need to compare this branch to that for any reason (mistakes, etc).

jdaugherty · 2026-04-17T15:43:28Z

FYI: I added this comment due to the micronaut mismatches. I'll add a work around for this for now (no javadoc so it's probably ok to force api compatibility). Hopefully they update on the micronaut side so there aren't any issues.

jdaugherty · 2026-04-17T16:07:21Z

Running this locally, I only had 1 test failure:

Which was due to OOM.

jdaugherty · 2026-04-17T16:07:44Z

@borinquenkid can you take a look at that failure?

borinquenkid · 2026-04-17T16:47:55Z

@jdaugherty I created a local task not checked in and needed this setup to run relaibli sub.tasks.withType(Test).configureEach { t -> │

Still TODO:

I need to understand why micronaut was choosing the wrong version of test containers (reason we put it in the bom)
need to take another pass at the out of tree updates
need to review hibernate / final PR state (may recreate in that case)

jdaugherty · 2026-04-21T12:56:52Z

@borinquenkid the latest round seems to have broken a lot of tests. Can you please take a look? I'd like to do another pass at this PR when you're done so we can actually review this functionality.

borinquenkid · 2026-04-21T16:16:01Z

I reset hard some of the changes because they touched core which affects other modules.
Here is an assessment of the limitations:

GORM Scalability Analysis & Multi-Tenancy Risk Profile

Metric	Safe Operating Range	High Risk Range	Critical Failure
Total Domain Classes	< 150	150 - 300	> 500
Total Tenants	< 200	200 - 500	> 1,000
Total API Objects	< 30,000	30k - 50,000	> 100,000

Summary for June Release

Suitability: Current code is stable for small-to-medium applications but NOT supported for Dynamic Schema SaaS due to the lack of tenant eviction/lifecycle management.
Mandatory Requirement: To achieve production-grade stability for June, the architecture must transition to a Class-Singleton Orchestrator where API instances are shared across all tenants.
Safety Ceiling: The 50,000 API object ceiling must be re-implemented as a mandatory safety gate until the orchestrator transition is complete.

My bom changes are really separate from this review. They fix a critical mistake in 7.0.x - you have to still override the hibernate 5 version instead of just using the bom. I'm going to look at pulling those changes out of this review so that the review is focused on hibernate alone.

This PR is currently blocked by #15605

Once that PR is merged, we will merge it up and then into this PR

jdaugherty · 2026-05-03T19:35:10Z

I need to split the micronaut bom into a hibernate5 & hibernate7 version as a next step. Will wait for this PR's latest round of tests to finish to see if anything else is missing.

@borinquenkid Please note that I removed testcontainers bom from our bom - we're inheriting from Spring and that's being included. The validateDependencyVersions task ensures that our bom matches the versions being imported and Spring by default imports 2.0.5 (see https://central.sonatype.com/artifact/org.springframework.boot/spring-boot-dependencies/4.0.6)

jdaugherty · 2026-05-03T20:52:14Z

FYI: I think I found out why testcontainers kept getting added to the boms - grails-forge is a micronaut app that still needs the older version. I've updated the micronaut dependencies to pull from the forge bom instead.

I split the micronaut bom into 2 - 1 for hibernate 5 & 1 for hibernate 7. Also, as part of the merge I lowered the memory back down and the tests are passing.

At this point, I need to review the licensing for the liquibase-hibernate import & then we can review this PR.

jdaugherty · 2026-05-04T00:35:10Z

@borinquenkid I need your help - do you have a base branch of the liquibase library that you imported? I need to clearly know which files were brought into the project (we can't put our own headers on them).

I'm assuming it's the files under: grails-data-hibernate7/dbmigration/src/main/java ?

jdaugherty · 2026-05-04T15:28:12Z

Per discussion with @borinquenkid 4.27 liquibase-hibernate is what was imported.

This means: https://github.com/liquibase/liquibase-hibernate/tree/v4.27.0-hibernate5 is the branch

- Rename snapshot/diff generators with 'Hibernate' prefix for clarity - Extract NoOpConnectionProvider and NoOpMultiTenantConnectionProvider from inner classes to standalone classes - Remove deprecated Hibernate 5 APIs: ClassLoaderDelegate, MetadataBuilderImpl, USE_NEW_ID_GENERATOR_MAPPINGS - Replace Class.newInstance() with Constructor.newInstance() reflection - Update Hibernate 7 API calls (MetadataBuilder, BootstrapServiceRegistry) - Update META-INF service files to match renamed classes - Update test fixtures for Hibernate 7 compatibility

jdaugherty · 2026-05-04T17:12:02Z

I've reimported the code under dbmigration-core (dropping the liquibase name since it's trademarked). I've followed the guidelines here: https://www.apache.org/legal/src-headers.html#3party Which explicitly say do not add source headers. I've made 3 commits to illustrate the original forked code vs what Walter updated.

I believe the licensing side of this is "right" now, but @jamesfredley do you think we should have someone in the ASF review this part of the contribution?

The belongsTo = [WqBiAuthor] edit was unnecessary scope-bleed in an H5 test file. Reverting to the original bare-class form belongsTo = WqBiAuthor restores the file to match 8.0.x and makes the H5 and H7 copies of the spec byte-for-byte identical again. Verified: spec passes 9/9.

Drop the extra blank line between the package statement and imports - an unintentional formatting artifact. Restores the single-blank-line convention. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The license header was unintentionally reformatted (two-space to one-space indentation). Restore the canonical Apache header to match 8.0.x; the test changes in this file are unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The PR had inverted this spec's relationship from many-to-one to one-to-many and renamed the test, while the class kept its ...ManyToOne... name and the H7 twin kept the original many-to-one form. That changed what the test covers and broke H5/H7 symmetry. Reverting restores the original many-to-one semantics and re-aligns H5 with its H7 twin (modulo the H5/H7 sequence-param difference). Verified: spec passes 1/1. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Reviewers (mattias_reichel, paulk_asert, scott) flagged that checker-qual was added as an api dependency though only @NonNull/@nullable are used and no Checker analyzer runs, so it leaked a runtime dependency to all GORM consumers for zero benefit. JSpecify is already on the compile classpath via the Spring Boot 4 BOM (the Spring 7 ecosystem standard) and one binder already used it, so the module was mixing two nullness libraries. Standardize on JSpecify: - swap the four checker-qual imports to org.jspecify.annotations - drop 'api org.checkerframework:checker-qual'; add 'compileOnly org.jspecify:jspecify' - remove the now-unused checker-qual BOM entries (both PR-added, absent on 8.0.x) Compiles, checkstyle passes, binder specs green (83/83). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The HibernateGrailsPlugin grailsVersion still declared '7.0.0-SNAPSHOT > *' on the 8.0.x branch (projectVersion is 8.0.0-SNAPSHOT). Update both the H5 and H7 plugins to '8.0.0-SNAPSHOT > *' to match the branch and keep the two plugins consistent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

@SInCE

This class is new in this PR (not on 8.0.x) and was authored by Walter Duque de Estrada, not Graeme Rocher. Fix the @author tag and correct @SInCE 7.0 to @SInCE 8.0 to match the branch. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Per review feedback, the binder-wiring method is mostly an orchestrator: a long run of 'TypeName x = new TypeName(...)' declarations where the type is repeated verbatim on the right. Converting the 36 locals to var removes that redundant left-hand repetition and makes the wiring far easier to read. No behavior change (var is compile-time inference); compiles and checkstyle passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

getCollector() compiles fine under the class-level @CompileStatic, so the method-level SKIP was unnecessary. Removed it (the method now inherits the class default). The SKIP on setupSpec() is left in place — that one genuinely needs it for the Spring bean-definition DSL. Verified: compiles and the plugin module tests pass (18/18). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The JSpecify migration removed the checker-qual dependency entirely, which broke compilation under JDK 25 (CI was green on JDK 21, red on JDK 25). JDK 25's javac requires checker-framework annotations such as @UnknownKeyFor — carried in the bytecode of dependencies like Hibernate's BytecodeProvider — to be resolvable on the compile classpath; JDK 21's javac tolerates them missing. Restore checker-qual as compileOnly (not api): it satisfies the compile-time annotation resolution JDK 25 needs without leaking a runtime dependency to GORM consumers, which was the original review concern. The JSpecify annotations on our own classes are kept. Verified under JDK 25 (Corretto 25.0.1): grails-data-hibernate7-core and all dependent H7 modules (grails-plugin, dbmigration, spring-orm, spring-boot) compile.

I cannot see that the TODO was removed.

matrei · 2026-06-24T09:55:51Z

I do disagree. By deprecating the current methods (findWithSql, findAllWithSql), and delegating to new methods (findWithNativeSql, findAllWithNativeSql), you are effectively changing the public API of GORM without discussion and consensus.

Also, please don't mark my review comments as resolved as it makes it very hard to find them.

…bernateEntity Clean-break rename agreed in weekly meeting: HibernateEntity (H7) now exposes only withSql(CharSequence) / withSql(CharSequence, Map) and withAllSql(CharSequence) / withAllSql(CharSequence, Map). The old findWithNativeSql / findAllWithNativeSql primary methods and the deprecated findWithSql / findAllWithSql aliases are all removed from the trait and from HibernateGormStaticApi (H7). In H5 the new withSql/withAllSql methods are added and the existing findWithSql / findAllWithSql methods are deprecated pointing to the new names; this keeps H5 backward-compatible while aligning the public API. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

H7 HibernateEntity now adds withSql/withAllSql alongside the existing findWithNativeSql/findAllWithNativeSql and deprecated findWithSql/findAllWithSql methods — no removal of existing methods. The new methods use the same private helper pattern as H5 (currentHibernateStaticApi()) instead of inline casting. H5 HibernateEntity is reverted to its original state — no new methods, no deprecation annotations added. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

The withSql/withAllSql additions are reverted. H7 HibernateEntity now exposes exactly what it had before: findWithNativeSql/findAllWithNativeSql as the primary methods and deprecated findWithSql/findAllWithSql as backward-compat aliases, all delegating through the private currentHibernateStaticApi() helper. Tests updated to use findWithNativeSql/findAllWithNativeSql and findWithSql/findAllWithSql accordingly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

H7's HibernateEntity now exposes the same public method names as H5 (findWithSql / findAllWithSql) while delegating internally to HibernateGormStaticApi.findWithNativeSql / findAllWithNativeSql. No deprecated aliases, no findWithNativeSql on the trait surface. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

These aliases are no longer needed: the HibernateEntity trait now exposes findWithSql/findAllWithSql directly, delegating to findWithNativeSql/ findAllWithNativeSql which remain the implementation in HibernateGormStaticApi. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
