[jboss-jira] [JBoss JIRA] Assigned: (JBMESSAGING-1294) Problem in jms message listener redelivery

Problem in jms message listener redelivery ------------------------------------------ Key: JBMESSAGING-1294 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1294 Project: JBoss Messaging Issue Type: Task Reporter: Tim Fox Assignee: Clebert Suconic Fix For: 2.0.0 Beta Currently core sessions have a batch size and can be set to auto commit acks. These is fairly complex and makes it hard to apply JMS message listener redelivery semantics. With a JMS message listener auto_ack or dups_ok, if a runtimeexception is thrown from onMessage the last message should be redelivered. An auto_ack session is marked as auto commit acks, so if we immediately rollback when receiving the exception, the last message is acked so is not redelivered. Solution here is never to auto commit acks. Sessions are always transacted (sends can be auto_acked or have concurrency problems when concurrently receiving and sending messages in a dups_ok session), and acks must be explicitly acked anc committed by the JMS layer. This should simplify the code too. Uncomment MessageConsumerTest::testExceptionMessageListener1 and 2 when this is complete
