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

well that's unfortunate.  we are using that feature (in a network of brokers).

>                 URL: https://issues.apache.org/jira/browse/AMQ-6456
>             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.
