> Key: JBTM-770
> URL: https://jira.jboss.org/browse/JBTM-770
> Project: JBoss Transaction Manager
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: JTS
> Affects Versions: 4.12.0, 4.6.1.CP06
> Reporter: Jonathan Halliday
> Assignee: Jonathan Halliday
> Fix For: 4.13.0, 4.6.1.CP08

> jts.TransactionImple constructors attempt to optimize the cleanup callback needed to remove entries from _transactions, bypassing the ORB for interposition scenarios:
> theTx = (TwoPhaseCoordinator) BasicAction.Current();
> if (theTx != null) {
> theTx.addSynchronization(new LocalCleanupSynchronization(this));
> } else {
> registerSynchronization(new CleanupSynchronization(this));
> }
> Unfortunately this does not work and leads to memory leaks on _transactions in certain cases. Specifically, where theTx is a ServerTransaction (i.e. extends ArjunaTransactionImple, which extends TwoPhaseCoordinator), the callbacks run (by ArjunaTransactionImple.do[Before|After]Completion()) are those in ArjunaTransactionImple._syncs, not the masked ones in TwoPhaseCoordinator._syncs. Thus using TwoPhaseCoordinator.addSynchronization registers a callback which is never invoked.
