Re: [RFC] [Java] QPID-2018 Clear queue doesn't clear acquired
messages which is a little confusing if that's all there is.

In order to accurately report the number of messages not deleted due to being in an acquired state a new 'clearQueueAndReportNumAcquired' method would need to be added to (Simple)AMQQueue, does that seem ok to everyone? The only real alternative is to start using the return value of the existing method in the MBean and have the console indicate how many messages were deleted, rather than how many were not. Thoughts?
Reporting how many were deleted seems reasonable to me, I don't see
much gain in introducing a new method to do something slightly
different.

I'd like to think I would have suggested this if I'd read the relevant
code first. ;)
