Subject [jira] [Commented] (AMQ-6209) Unmatched messages on consumer queues when using SubQueueCacheSelectorPlugin in network of browsers

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

I ran your updated test and it does indeed pass, however it also passes without the fix applied
which is a problem as it doesn't validate the problem and protect the fix into the future.

> 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.
