AMQ 7: messages accumulate on topic, even in the absence of durable subscribers

Solution Verified - Updated -

Issue

In an AMQ 7 installation, a message destination is predefined as a JMS topic like this:

     <address name="foo">
       <multicast>
         <queue name="foo" />
       </multicast>
     </address>

If messages are published to the topic foo then they appear to accumulate, even when there are no subscribers -- even when there have never been any subscribers. This is unexpected because, in the absence of durable subscribers, there is no need to accumulate messages for a JMS topic.

Environment

  • Red Hat JBoss AMQ
    • 7.0
      The problem does not affect A-MQ 6.x, because it is configured differently
