Aidan Skinner commented on QPID-2193:
-------------------------------------

OK, I can see where you're coming from, we don't need to be Tufty. How about 
showing a quick warning the first time they do this on older brokers in any 
particular instance? References to appendages optional. ;)

> Java brokers previous to 0.6 do not support deletion of arbitrary messages, 
> only the 'first message on the queue' at any given time. This was not exposed 
> in the updated console due for release with 0.6 (where the broker now does 
> support deletion of arbitrary messages). This decision was made because by 
> its very nature the method cannot guarantee which message would be deleted 
> when it is executed, as any queue activity could alter which message is at 
> the head of the queue. However, users may have come to expect this method to 
> be present, and so it should be exposed for older brokers that lack the 
> ability to exactly specify which messages should be deleted.
