[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-660) Race Condition Between Session.close and Session.commit or Session.rollback

[Ovidiu Feodorov (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBMESSAGING-660?page=comments#action_12347966 ] 
            
Ovidiu Feodorov commented on JBMESSAGING-660:
---------------------------------------------

The race condition occurs while running ConcurrentCloseStressTest (thanks, Clebert).

The root cause seems to be the fact that ChannelSupport.deliveryInternal() main while loop doesn't synchronize access to messageRefs strongly enough, so cancellations that arrive to the channel while looping may break the consistency and cause the chanel deliver the same message again and again. 

Trace snapshot attached.
