[jboss-jira] [JBoss JIRA] Closed: (JBMESSAGING-809) Extra message created if server fails right after send is completed

Extra message created if server fails right after send is completed ------------------------------------------------------------------- Key: JBMESSAGING-809 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-809 Project: JBoss Messaging Issue Type: Bug Affects Versions: 1.2.0.Beta2 Reporter: Clebert Suconic Assigned To: Clebert Suconic Priority: Critical Fix For: 1.2.0.CR1 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.
