Extra message created if server fails when send and ACK are synchronized
------------------------------------------------------------------------

                 Key: JBMESSAGING-809
                 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-809
             Project: JBoss Messaging
          Issue Type: Bug
            Reporter: Clebert Suconic
         Assigned To: Ovidiu Feodorov


Imagine two threads... producer/consumer...

If the server crashes when both ACK and send are still coming back from the execution (at the same time)... there is a chance of creating a message.

I have created MultiThreadFailoverTest::testFailureOnSendReceiveSynchronized for this... But I have seen testMultiThreadFailover failing ocasionally.

testFailureOnSendReceiveSynchronized poisons the server is a special way to cause the synchronization issue in a predictable way.
