title: Message redelivery ibm mq
body: <p>I have a system that reads messages from a IBM MQ. From this queue we sometimes get corrupt data. If a message has failed the next time it is read the listener will wait 5 minutes before proceeding. When a message has failed 3 times it is put on a Backoff-queue. The JMSContainerFacotry is set up to run max 10 in parallell. This means if we get a big batch of corrupt messages these messages take 10+ minutes each to reach the Backoff-queue (which is ok), but they end up consuming all the threads so other messages must wait for all the corrupt to reach the Backoff-queue before being processed. I want to remove the wait() from the listener so that this doesnt block threads, but that failed messages still wait 5 minutes before popping back up. </p>
  
  <p>I know that with ActiveMQ you can tell the queue to wait 5 minutes before popping the same message again, with IBM MQ I dont have that possibility. Is it possible to put failed messages to the back off the queue? Now failed messages seems to pop in front of new ones. Or set the jmspriority on failed messages lower. So that if there is messages that have yet to fail will get popped from the queue before those that have failed? </p>
  
  <p>My listener is about so: </p>
  
  <pre><code>@JMSListener()
  public void listen(Object message) {
  TextMessage textMessage = (TextMessage) message;
  
  if (textMessage.getIntProperty("JMSXDeliveryCount") &gt; 1) {
   //pause for 5 minutes
  }
  
  //buisness logic
  
  }
  </code></pre>
  
  <p>The in-queue is a IBM MQ. AS is Jboss 6. </p>
