Description

When you "purge" queue from web admin console, it zeroes queue message
counter. But if you have an active consumer at that time which
pre-fetched messages than your consumer will keep sending ack as it
process messages from its buffer. ActiveMQ will keep decrement counter
upon receiving each ack. So when consumer is done queue will show
MINUS<consumer buffer size>.
