james commented on AMQ-6456:
----------------------------
if we could confine our exclusive consumers to a single broker, then we would
essentially be implementing the exclusive consumer feature on our own.
technically, we _could_ do it (non-trivial on our end), but we thought we were
getting the feature out of the box with activemq.
> Exclusive consumer may stop consuming in broker network

> Key: AMQ-6456
> 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
> Attachments: exclusive_consumer_patch.txt
>
>
> 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.
