Thre is a bug in the JBossMessageConsumer which prevents to unset the message
listener. We'll fix it.
Please not however that even with this bug fixed, your test case may not work.
From MessageConsumer.setMessageListener() javadoc:

| The effect of calling MessageConsumer.setMessageListener while messages are
being consumed by an existing listener or the consumer is being used to consume
messages synchronously is undefined.

You should stop your queueConnection to prevent message consumption before
unsetting the message listener to have a correct behavior.
