Subject [jira] [Commented] (AMQ-5189) Rollback on XASession when closing back to pool
Date Sat, 17 May 2014 08:23:14 GMT

    [ https://issues.apache.org/jira/browse/AMQ-5189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14000709#comment-14000709

Benjamin Graf commented on AMQ-5189:
------------------------------------

A solution might be to register a PooledSessionEventListener in XA synchronisation which does
the ignore and xa flagging onSessionClosed.

> If you have a pool of XASession under load (heavy load might be necessary) I register
sometimes following Exception "Cannot rollback() inside an XASession" in afterCompletion synchronisation.
After some analysis and patching with logging I recognized that the session object is returned
back to pool before setting the xa flag back to false. This leads to the effect that this
session gets be used again by another thread while the earlier one switches the xa flag to
false.
