Oops, missed that bit. Both QPid and RabbitMQ have the concept of an 
"exclusive" consumer - a consumer which won't let anything else share 
the queue it's consuming from. Somehow you're inadvertently creating 
one; it sounds like you don't want to.

Unfortunately I'm no expert on the JMS API (understatement); it's not 
obvious how you might create a non-exclusive consumer (I would have 
expected that would be the default, but hey...)
