New Revision: 423755

URL: http://svn.apache.org/viewvc?rev=423755&view=rev
Log:
To help with the development of Virtual Topics I've added a test case to confirm that destinations are lazily created when a consumer is created. For more background see the dev thread:  http://www.nabble.com/Re%3A-Virtual-Topics-%28was-Re%3A-Failover-topic-subscribers%29-tf1942508.html#a5404863
