Subject Re: ActiveMQ.Advisory.MessageConsumed.TempQueue problem
Date Tue, 10 May 2011 11:12:00 GMT
the purge is necessary to release the resources associated with the
temp queue. see: https://issues.apache.org/jira/browse/AMQ-2616

but I think you have a good point here. the advisory for consumed
should be conditional on the message getting acked by a consumer.

It should be easy enough to fix because subscribers are removed before
the queue is purged, so
making the advisory conditional on having some consumers should do it.

Can you open a jira issue to track this. If you have a junit test case
that can verify the behavior you want it would be a great help.
