[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5315) AuditJoinTable rows are no longer flushed to the database

[Erik-Berndt Scheper (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37502#action_37502 ] 

Erik-Berndt Scheper commented on HHH-5315:
------------------------------------------

Well, I've tried to reproduce this using the Envers test suite, but failed (until now). I have a few ideas why this might be the case. One suspect is the behaviour of the transaction manager in the test suite (in the sense that its behavious is different from an XA enabled JTA transaction manager). Does that make sense?  Another suspect is that I'm using JPA with a Spring persistence context.

Perhaps Envers is using the actionqueue in a way that was never intended? 

I worked around the issue by adding an extra Spring AOP interceptor before the spring tx interceptor. This extra inceptor does an extra flush and then everything works fine. 
Another thing I tried was to add an extra transaction synchronization and add the flush there, but to my surprise that did not work. 

Anyway, I did succeed to reproduce this in an Eclipse project with a couple of open source third party libraries. I could add that project to this issue with some extra info if this helps.

Note: this issue also affects 3.5.3 and current trunk (3.6.0-snapshot).

> 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.
