      Known Issues

      • As of the 2.5.2 patch set, builds will no longer be published to the Maven repository. Builds will continue to be published
      • Bug 374771

        Some TREAT expressions in the where clause will not work properly.

      • Bug 404294

        Application managed persistence contexts (EntityManager) using JTA transactions must join the active transaction where as previously it automatically joined. Without the joinTransaction call, the changes made in the Entitymanager will not be commited when the JTA transaction compltes.

      • Bug 407570

        Attribute defined in an unmapped POJO and inhertited by an Entity, may not be be persisted. Simplest solution is to ensure that all the persisted attributes are mapped (ie. @MappedSuperclass). See the bug for futher details.

      • Bug 408015

        Redploying a JPA-RS persistence unit will not always update the persistence unit with new mappings. Two workarounds are described in the bug.

      • When running EclipseLink 2.5 in Glassfish 4.0, you must specify a valid datasource in the persistence.xml through either the jta-data-source or non-jta-data-source tags.
