james commented on AMQ-6456:
----------------------------

I'll see if i can get something going.  i tried to create a network broker 
related test before (different issue) and couldn't recreate the problem in a 
unit test.

> Exclusive consumer may stop consuming in broker network

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.9.1, 5.14.1
>            Reporter: james
>            Priority: Critical

>
> When exclusive consumers are restarted in a network of brokers, the "chosen" 
> consumer may shift from one broker to the next.  In order for existing 
> messages to be consumed, they must be forwarded from the broker on which they 
> currently exist to the broker on which the chosen consumer now resides.  
> However, the ConditionalNetworkBridgeFilter incorrectly decides that it 
> should not forward the messages and they end up getting stuck on the old 
> broker.
> We found the issue in 5.9.1, but the relevant code looks unchanged in the 
> current 5.x release.
