> When using a core api ClientConsumer using pre-acknowledge message acknowledgement, the
broker sends out CONSUMER_SLOW notifications (continuously) for that client.  According to
JConsole, the queue for the client shows all messages being acknowledged, and the address
for the queue shows address size = 0 (not backing up).  The ClientSession used to create the
consumer was constructed with the pre-acknowledge constructor param=true:
> ...
> ClientSession session = factory.createSession(false, true, true, true);
> I also noticed that this does not happen using a STOMP client using the auto acknowledgment
subscription (with "ack:auto" header in SUBSCRIBE frame).
