Subject Re: 5.2, Problems Deleting a Queue
Date Tue, 13 Jan 2009 02:01:09 GMT

No, but this a part of a Network of Brokers.  I just tested on one of our AMQ
servers that is not on a network of brokers and the problem occurs there
too.  Here's the order of the test I just performed:

 1.) Login to the AMQ Web Console
 2.) Create a Queue using the Web Console
 3.) Use Ant to launch a producer and send a bunch of messages to the newly
created Queue
 3.) Use Ant to launch a consumer to recieve those messages.
 4.) Close both the producer and consumer(now 0 pending messages, non
 5.) Delete the Queue from the Web Console
 6.) Restart the Broker, Queue reappears.
 7.) Delete Queue from Web Console one more time.
 8.) Use Ant to launch a consumer, presented with an error "User consumer is
not authorized to create: queue://Matt.Test" (I have security enabled to
disallow producers and consumers from lazily creating Queues or Topics.
 9.) Use Ant to launch a producer, should be presented with same error. 
Instead Broker accepts the messages. However, neither JMX or the Web Console
show this Queue in existence since the last delete.  10.) Restart the
broker, the Queue will reappear, empty.
