I assume you mean QPID-601, not QPID-602.

I had thought the TopicSessionTest failure was an example of the race 
condition, however your explanation in another post also accounts for 
that failure.

I haven't tested this myself, but in theory a long enough Thread.sleep 
at the end of ConcurrentSelectorDeliveryManager.populatePreDeliveryQueue 
should make the race condition easy to reproduce because at that point 
the Subscription has not been added to _subscriptions, so any messages 
delivered at that point will be stranded in the _messages queue.
