> virtualSelectorCacheBrokerPlugin fails on "browse" action
> ---------------------------------------------------------
>
> Key: AMQ-7312
> URL: https://issues.apache.org/jira/browse/AMQ-7312
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.15.10
> Reporter: Dany LECOQ
> Assignee: Jean-Baptiste Onofré
> Priority: Critical
> Fix For: 5.15.11
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We have a VirtualTopic "VirtualTopic.multi_dest" and 2 consumers :
> * Consumer.alpha.VirtualTopic.multi_dest
> * Consumer.beta.VirtualTopic.multi_dest
> Message producer send messages on that vTopic with various "tenant" header
> value.
> Each consumer use a selector to receive only desired data :
> * tenant='alpha' for Consumer.alpha.VirtualTopic.multi_dest
> * tenant='beta' for Consumer.beta.VirtualTopic.multi_dest
> To avoid to get many pending message on each consumer queue, we activated
> selectorAware="true" in broker settings.
> To avoid to lose message on temporary consumer deconnection, we activated
> virtualSelectorCacheBrokerPlugin plugin.
> Steps to reproduce bug :
> * launch message producer and both message consumers alpha and beta
> * stop alpha consumer
> * notice on console pending messages on alpha queue increase
> * if we restart alpha consumer, all pending messages are consumed => ok,
> only messages matching selector were in queue
> * restop alpha consumer
> * go on console and click on "Browse" link for alpha consumer queue
> * restart alpha consumer => it will consume pending messages matching
> selector
> * notice there are other waiting messages that do not match selector, so the
> consumer queue is fastly full of useless messages => ko
> * even after broker restart, the alpha consumer queue continues to receive
> message that do not match selectors => ko
>
> After code analysis, I notice "Browse" action create a new consumer on queue.
> In virtualSelectorCacheBrokerPlugin, the addConsumer method update
> "subSelectorCache" variable with 'TRUE' selector.
>
> A pull request is submitted to fix that issue
> ([https://github.com/apache/activemq/pull/395]), could you merge it for the
> next patch 5.15.11 ?
