Matthew B. Jones updated HHH-5315:
----------------------------------

    Attachment: jta_compatability.txt

Attached is an Eclipse workspace patch for envers trunk. This resolves the issue with using Envers within the context of JTA. Yes, adding em.flush() everywhere in your business logic does avoid the issue, but this patch reverts Envers back to some earlier code in the way it subscribes for Hibernate events.

> In Hibernate core 3.5.1 issue HHH-3543 was fixed by using BeforeTransactionCompletionProcess instead of a transaction synchronization. I have found that since this change, rows in AuditJoinTables are no longer flushed to the database. (Envers 3.5.0 final works fine).
> I can work around the issue by adding a manual entityManager.flush() or by setting the flushmode to manual. 
> I have noticed that AuditProcess.java already executes a flush() statement, but this does not seem to suffice. I believe this is caused by the fact that during the doBeforeTransactionCompletion() extra WorkUnits are added to the hibernate ActionQueue (PersistentCollectionChangeWorkUnit) which process the AuditJoinTables.
