actually the error was this piece of code | if (checkDLQ(ref)) | { | LinkedList<MessageReference> toCancel = queueMap.get(ref.getQueue()); | | if (toCancel == null) | { | toCancel = new LinkedList<MessageReference>(); | | queueMap.put((QueueImpl)ref.getQueue(), toCancel); | } | | toCancel.addFirst(ref); | } actually it should be if (ref.getQueue().checkDLQ(ref)) | { | LinkedList<MessageReference> toCancel = queueMap.get(ref.getQueue()); | | if (toCancel == null) | { | toCancel = new LinkedList<MessageReference>(); | | queueMap.put((QueueImpl)ref.getQueue(), toCancel); | } | | toCancel.addFirst(ref); | } We always call the checkDLQ(..) method is always called for the same queue not the queue for the ref. This explains the errors with the AddressSettings tests I'm currently writing as well. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221529#...
