> We used MirroredQueues so that we can monitor what's going on using a simple Topic client
we wrote. When we click 'Purge' on the queue in the web admin interface, we get a Java exception:
org.apache.activemq.broker.region.virtual.MirroredQueue$1 cannot be cast to org.apache.activemq.broker.region.Queue.
We are able to delete the queue, but then our listener classes do not auto-reconnect for up
to 5 minutes (our own code for that to work around issues with ActiveMQ.Net bindings).
