Most changes applied to both versions. Of note are:

  • HHH-9312 fixed a database connection leak with JTA transaction tracking caused by a transaction timeout detected by a background thread with the transaction rolled back immediately; the background thread was not closing the database connection when Synchronization.afterCompletion(int status) was called; instead, the database connection was not closed until the next application request that used the affected Hibernate session.
  • HHH-9387, HHH-9389, and HHH-9390 fixed some bugs in generated table and foreign key column names for collections when JPA annotations were used. Because these fixes could break existing applications (that rely on the incorrectly generated table and column names) they are not fixed by default. A new API (NamingStrategyDelegator) was added (HHH-9388) to enable these fixes because the NamingStrategy API was too inflexible to allow making changes without causing regressions when a custom NamingStrategy is used. NamingStrategy has been deprecated (HHH-7079 in favor of this new API. Documentation for the NamingStrategyDelegator API has not been added to the manual yet, and the API is not supported in the standalone schema tools yet. Both will be added in 4.3.8 and 4.2.17. For now, you can see details about enabling the fix in the Jira issues.
  • HHH-9305 fixed various bugs in SQL generated for HQL queries that contain an implicit join. The following are examples of HQL affected by this bug are:
       // e.department is implicitly joined in the "select" clause, and is explicitly joined in the "from" clause
       select e.department from Employee e inner join e.department

       // a.zoo is implicitly joined in the "select", "where", and "order by" clauses
       select distinct a.zoo from Animal a where a.zoo is not null order by

There were several fixes made to 4.3.7 (only):

  • HHH-8839 fixed a bug that caused an IllegalStateException when rendering the SQL for loading an entity with an eager map having an entity key.
  • HHH-8895 fixed a bug that caused a SQLGrammarException when enabling a filter that is defined on a @MappedSuperclass hierarchy because the filter condition was getting applied to all tables in the hierarchy, instead of just one where the filter is defined.
  • HHH-3868 fixed a bug that caused NullPointerException when merging an entity Merging transient entity with an @Embeddable property containing a @org.hibernate.annotations.Parent mapping.

Changes to 4.3.6.Final were mainly bugfixes with some performance improvements. A new Hibernate module was added to provide support for HikariCP connection pool (HHH-8869).

The following bugfixes applied only to 4.3.6.Final:

  • HHH-8818 fixed a regression introduced in 4.3.0.Final causing Hibernate to not be able to find the JNDI DataSource.
  • HHH-4700 fixed a bug using an HQL CASE expression containing a parameter in the THEN clause, and HHH-6747 fixed a bug rendering a SimpleCase using CriteriaBuilder.selectCase( arg ). Both caused ClassCastException to be thrown.
  • HHH-8885 fixed a bug causing a NullPointerException when MapJoin.key() is used.
  • HHH-8980 fixed a bug where an entity was not found if a joined subclass had a non-nullable many-to-one or one-to-one association.

The following bugfixes applied to both 4.3.6.Final and 4.2.15.Final:

  • HHH-9280 - caused the table name computed for an @ElementCollection to use the entity class name instead of the specified entity name.
  • HHH-8310 caused class loading problems due to a Spring bug that changed the context classloader to one that could not locate Hibernate Lob proxy classes (BlobProxy, ClobProxy, NClobProxy, SerializableBlobProxy, SerializableClobProxy).
  • HHH-9106 (for 4.3.6.Final) and HHH-9261 (for 4.2.15.Final) optionally allows multiple representations of the same entity to be merged (e.g., loaded from different sessions).

Hibernate ORM 4.2.14.Final was just released! Please see the full changelog for more information:

Another 4.2.x version was necessary to make the following changes:

  • HHH-9255 reverts HHH-9222, which caused incorrect SQL to be generated when bulk deleting collections that use a property-ref;
  • HHH-9252 fixes a bug where an error executing a batch did not abort the rest of the batch.

Another 4.2.x release was necessary to fix the following:

  • HHH-9154: fixes a regression introduced in 4.2.12 that broke HQL queries with a named parameter that is an HQL keyword;
  • HHH-9204: fixes a regression introduced in 4.2.12 that changed the method signature for an SPI, AbstractCollectionPersister.doProcessQueuedOps(PersistentCollection, Serializable, SessionImplementor);
  • HHH-9170: fixes a regression introduced in 4.2.8 that enables the second-level cache for a StatelessSession in some cases.

In addition, there were several improvements and minor fixes.

Hibernate Core 4.0.0.CR5 has just been released.

We are releasing a new CR because of a classloading issue (HHH-6715) affecting applications that integrate with Hibernate. In addition, some bugs were fixed and some improvements were made that should improve performance.

For more details, see the JIRA release notes.

The artifacts have all been published to the JBoss Nexus repository under the org.hibernate groupId at
