JMS Courrier does not support transacted mode
---------------------------------------------

                 Key: JBESB-1438
                 URL: http://jira.jboss.com/jira/browse/JBESB-1438
             Project: JBoss ESB
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Process flow, Rosetta
    Affects Versions: 4.2.1
            Reporter: Jiri Pechanec
         Assigned To: Mark Little
            Priority: Blocker
             Fix For: 4.2.1 CP1


JMS Courrier (deliver side) operates only with non-transacted queue sessions. This prevents jBPM integration to work correctly. The problem can be sketched this way
1) The message is received via JMS/JCA listener, transaction is started
2) jBPM process is invoked
3) jBPM process sends message (calls service) in non-transacted mode
Three situations can happen
1) Exception is thrown later, it means that global transaction is rolled back but another service was already invoked - BUG
2) jBPM process goes to the wait state and waits for response from ESB, global transaction is committed, called service sends back signal to continue process - OK
3) jBPM process goes to the wait state and waits for response from ESB, called service sends back signal to continue process - but the global transaction was not committed yet - BUG

This is key feature to have ESB/jBPM integration working safely.
