In Subscription.java accepts method at line 71 the
following code appears
< if (noLocal ) {
if(
header.producerClientId.equals(connectionToken.getClientID()))
return false;
}
>
In Subscription.java ConnectionToken never gets initialised
and hence never returns false and hence messages are accepted.

New information:
The cache problem occurs when the same client
subscribes and publishes to the same topic, regardless
of the noLocal flag.

After much more testing it appears the problem has
something to do with the noLocal flag in the
createSubscriber() method.
When I set noLocal to true I see the MessageCache
continue to grow. When I set noLocal to false then the
MessageCache works as expected messages get added
and removed.
TopicSubscriber subscriber = session.createSubscriber
(topic, null, true); // cache continues to grow
TopicSubscriber subscriber = session.createSubscriber
(topic, null, false); // cache works correctly
