First in the pom.xml, if you use <version>5.11.0.redhat-621084</version> the problem doesn't show. Once you change it to <version>5.11.0.redhat-621090</version> or <version>5.11.0.redhat-621107</version> the junit test will fail.

The main code goes like this:

Ln41   count = getMessageCount(producerQueue, session);
         System.out.println("first count "+ count);
         assertEquals(1, count);

Ln44   Thread.sleep(WAIT_TIME +  1000);

          count = getMessageCount(producerQueue, session);
          System.out.println("second count "+ count);
Ln48    assertEquals(0, count);

Using 5.11.0.redhat-621090 or later build, ln48 assertion fails.

If you increased the sleep time to 30 secs (ln 44: Thread.sleep(WAIT_TIME + 30000), looks like it is working properly.
Also, looking at the jmx mbean, and it looks like it is reflecting immediately.
