2) The meaning/usage of DLQ : In HornetQ, there are just Dead letter Addresses. But from
the point of view of a JMS client (like MDB) which are just aware of (JMS) queues and
(JMS) topics, how would the MDB subscribe to a dead letter (JMS) queue. I am still looking
at the hornetq configs in AS and reading through the docs to see how the (hornetq) DLA is
being setup. I guess, there needs to be some layer which sets up a (HornetQ) queue
subscription to the DLA to make it look like the (JMS) DLQ.
We can stop worrying
about this part now, because the reason why the DLQ/DLA is +not+ being triggered for the
MDB, is because of this bug/config issue in HornetQ

I quickly hacked the MessageReference#getDeliveryCount() impl to return a value higher
than the max-delivery-count and I could see that the message is redirected to the DLQ and
the EJB3 test passes. So it's just a matter of fixing that issue mentioned in the
other thread.
As for the other questions raised in this thread, they are still valid.
