Client deadlock in AMQ 4.1.0
In 4.1.0 there's deadlock on connection failover. There is the scenario:
1. Client consumes message using message listener
2. Conection is lost
3. Client sends message to another queue from messagle listener and waits
untill connection is restored.
4. Reconnect task blocks on reconnecting.
This bug is new to 4.1.0. The problem is in ActiveMQMessageConsumre.dispatch
. There is new lock on unconsumedMessages.getMutex() . So the reconnect task
cannot invoke ActiveMQMessageConsumre.clearMessagesInProgress(), because
lock is acquired by message listener, which waits untill message is send
(untill connection is resumed). Here is stack traces:

Re: Client deadlock in AMQ 4.1.0
Posted by James Strachan <ja...@gmail.com>.
Thanks for the great stack trace! That really helps figuring this out.
I've just committed a fix to trunk which I think should fix this issue
- please could you retest with trunk and see if that fixes your issue?
