[jbossts-issues] [JBoss JIRA] Updated: (JBTM-696) NPE in TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:235)

NPE in TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:235) ------------------------------------------------------------------------- Key: JBTM-696 URL: https://jira.jboss.org/jira/browse/JBTM-696 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public(Everyone can see) Components: JTA Affects Versions: 4.2.3.SP7, 4.6.1 Environment: Linux Reporter: Jörg von Frantzius Assignee: Andrew Dinn Fix For: 4.2.3.SP8, 4.6.1.CP01 In http://community.jboss.org/thread/142942?tstart=0 I've been told that JBOSS 4.2.3GA comes with JBossTS 4.2.3.SP7. We managed to see this exception with JBoss 4.2.3GA : Caused by: java.lang.NullPointerException at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:235) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.end(TwoPhaseCoordinator.java:86) at com.arjuna.ats.arjuna.AtomicAction.commit(AtomicAction.java:177) at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate(TransactionImple.java:1389) at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction.java:135) at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDelegate.java:87) at org.jboss.tm.usertx.client.ServerVMClientUserTransaction.commit(ServerVMClientUserTransaction.java:140) at com.artnology.managedobject.impl.ManagedObjectManager.commitUnderlyingTx(ManagedObjectManager.java:5292) at com.artnology.managedobject.impl.ManagedObjectManager.commitTransaction(ManagedObjectManager.java:4838) What's a bit unusual about our transaction is that it does a lot of work during beforeCompletion, which might exceed the transaction timeout (but I don't know for sure that it did). Maybe a long user code activity during beforeCompletion can cause this confusion of _synchs possibly already having been nulled out.
