When testing durable subscibers, I first publish a message to a subscriber to be sure it can receive messages. Checks out ok. Then I bring the subscriber down with subscriber.close() where subscriber is an instance of MessageConsumer. Next, I publish another message while the subscriber is down, then I bring the subsciber back up and wait 10 seconds for a message...no message comes. To be sure the everything is working properly, I create another message and publish it, the subscriber has no problem receiving it. My question is where has the second message gone? I would think that the message would have been queued up some place to be sent out again but that is not the case. Please let me know if I am looking at this totally wrong.
