> Key: NXP-2811
> URL: http://jira.nuxeo.org/browse/NXP-2811
> Project: Nuxeo Enterprise Platform
> Issue Type: Bug
> Reporter: Thierry Delprat
> Assignee: Thierry Delprat
> Fix For: 5.2 M4
>
> Attachments: ejb3-interceptors-aop.xml.diff,
> nuxeo-jboss-interceptors-4.2.3.GA.jar

> Since DocumentManagerBean implements SessionSynchronization we can see
> multiple warning in the logs each time the DocumentManagerBean gets released :
> TwoPhaseCoordinator.afterCompletion - returned failure ....
> This WARNING is caused because the JTA Synchronizer registred by the Jboss
> SessionSynchronizationInterceptor try to call afterComplete method on the
> bean just after the RemoveInterceptor terminated the bean.
> This is caused by 2 JBoss bugs :
> 1 - since JTA spec does not really allow to order the synchronizer there is
> no way to be sure the Remove synchronizer will be called after the Session
> synchronizer
> Actually, the arjuna implementation stored synchronizer in a set that is
> ordered by the dynamically generated UUID ....
> 2 - the JBoss interceptor that register the Session Synchronizer has a bug :
> it register the synchronizer each time a method of the bean is called
> => since arjuna has no way to detects that the synchronizer is the same
> (dynamically generated UUID) the synchronizer stack is filled with plenty of
> SessionSynchronisers
> => it gives fewer chances to have the synchronizer properly ordered
> => this make the warn being displayed several times
> => this is bad for perfs
