There is indeed a bug. If you change the acceptMode to 
ACCEPT_MODE_EXPLICIT you will see the dequeues reported as expected.

However with ACCEPT_MODE_NONE, the message is not correctly dequeued on 
being acquired as it should be (the explicit accept in this case would 
then be ignored). It is removed from the in-memory delivery queue (which 
is why it doesn't get redelivered to subsequent clients).

I've raised a Jira (https://issues.apache.org/jira/browse/QPID-2089) and 
will endeavour to get that fixed shortly. Thanks for raising this!
