Sergio Bossa commented on AMQ-3485:
-----------------------------------

The problem is not about consuming from *multiple consumers* the *same* message: it is about consuming *different messages*.
That is, subsequent consumers always return null if there's a previous consumer with a non committed message, which doesn't make sense, as if you want to preserve ordering with that, you should really throw an exception rather than fail silently.
Is it clearer now?

> When I have a transacted Session, as it is single threaded I can't create two MessageConsumer to the same Destination. But if I create a MessageConsumer to a Destination and then I close it, then I should be able to create a new MessageConsumer to the same Destination. This is working fine in active mq 4.1.2 but it doesn't work in 5.5.0. It allows to create a second MessageConsumer but that seconde MessageConsumer always returns null when the queue has messages.
> i.e:
> Session session = .... //transacted session
> Destination dest = .... 
> MessageConsumer mc = session.createMessageConsumer(dest);
> Message message = mc.receive(); // message received ok
> mc.close();
> mc = session.createMessageConsumer(dest);
> Message message = mc.receive(); // message is null
> Thanks, Pablo.
