JPA afterCompletion sync may be called from non-application thread, resolve concurrency concern ----------------------------------------------------------------------------------------------- Key: AS7-6586 URL: https://issues.jboss.org/browse/AS7-6586 Project: Application Server 7 Issue Type: Feature Request Components: JPA / Hibernate Affects Versions: 7.1.1.Final, 7.1.2.Final (EAP), 7.1.3.Final (EAP) Reporter: Scott Marlow Assignee: Scott Marlow Fix For: 8.0.0.Alpha1 For transaction scoped entity managers, the closing the of entity manager is deferred until after the transaction completes. It is possible that the transaction manager/service may call the Transaction sync from a non-application thread (tx timeout reaper thread or normal completion in remote propagated tx case). Guards need to be added to make sure that a tx timeout, doesn't interfere with normal application usage of the entity manager.
