>             Project: ActiveMQ
>          Issue Type: Bug

>            Priority: Minor

> I have enabled <policyEntry tempQueue="true" advisoryForConsumed="true" /> in the
broker so I can subscribe to "ActiveMQ.Advisory.MessageConsumed.TempQueue.>" to get notified
of messages consumed on a tempQueue/s. When client shuts down 
> if remaining messages are in the tempQueue an advisory message is generated and send
to the ActiveMQ.Advisory.MessageConsumed.TempQueue topic for each message for that tempQueue.
The same will happen if purge() is called on a TempQueue or Queue for example through JMX.
 
> In my application I need to know if a message is consumed by a client but I can not differentiate
between a client "ack" massage and one "ack" by the broker when the tempQueue is "disposed"
looking to the message sent to the ActiveMQ.Advisory.MessageConsumed.TempQueue... . 
>  
> Looking at the code for TempQueue and Queue this is the sequence :
> TempQueue.dispose(context) --> purge() --> removeMessage() -> acknowledge()
--> messageConsumed() 
> This is kind of a conceptual issue since myself consider that removing a message due
a purge or a tempQueue cleanup should not trigger a messageConsumed advisory.
