Timothy Bish commented on AMQ-6209:
-----------------------------------

I gave the patch a quick spin and the test fails with the below:

So you might need to do some more work on the test to ensure it's sound.

>                 Key: AMQ-6209
>                 URL: https://issues.apache.org/jira/browse/AMQ-6209
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.13.2
>            Reporter: Patrik Dudits
>
> When using SubQueueSelectorCachePlugin to preserve consumers' selectors in network of
brokers, the queues start matching all messages after consumers failover between brokers.
> The underlying reason is, that {{SubQueueSelectorCacheBroker}} would cache selector {{TRUE}}
for connected demand subscription, and therefore will permanently match all messages even
if actual consumer reconnects.
> Additionally, browsing the queue will also cause {{TRUE}} selector to be persisted.
