Clebert Suconic commented on JBMESSAGING-702:
---------------------------------------------
On my local copy I have fixed the issue by removing the mainLock.
As this is only activated from a failover, this should be okay, since failover will be
holding a writeLock.
public void copyState(MessageCallbackHandler newHandler)
{
//synchronized (mainLock)
//{
this.consumerID = newHandler.consumerID;
this.consumerDelegate = newHandler.consumerDelegate;
this.sessionDelegate = newHandler.sessionDelegate;
this.buffer.clear();
//}
}
Dead Lock condition on MessageCallbackHandler when failover is being
executed

Key: JBMESSAGING-702
URL: http://jira.jboss.com/jira/browse/JBMESSAGING-702
Project: JBoss Messaging
Issue Type: Bug
Reporter: Clebert Suconic
Assigned To: Clebert Suconic
If a failover happens when an auto ACK, is returned from MessageCallbackHandler (look at
the thread dump) a dead lock might happen:
