---------------------------------------
Assignee: (was: Clebert Suconic)
> Possible durable message count error with retryMessages()
> ---------------------------------------------------------
>
> Key: ARTEMIS-2564
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2564
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.10.1
> Reporter: Anders Andersson
> Priority: Minor
>
> There is a possible bug with retryMessages() JMX call
> Step 1: Send messages to a queue
> bin/artemis producer --user me --password mypassword --destination
> queue://MESSAGING.QUEUE.3 --message TEST
> Durable message count is 1000 and Durable persistence size is 394000. Message
> count is 1000 and FirstMessageTimestamp is 1574947152841 for this queue.
> First Message As Json has JSON text inside it.
>
> Step 2: Retry the messages
> It makes no sense to retry messages that hasn't gone to DLQ but that was what
> I did:
> [http://my.happy.machine:8181/console/jolokia/exec/org.apache.activemq.artemis:broker=!%22amq-c!%22,component=addresses,address=!%22MESSAGING.QUEUE.3!%22,subcomponent=queues,routing-type=!%22anycast!%22,queue=!%22MESSAGING.QUEUE.3!%22/retryMessages()]
> Got 1000 back
> FirstMessageTimestamp is empty and FirstMessageAsJson is [{}] other than that
> all fields above is unchanged.
>
> It looks to me that when retryMessages() runs on messages that have not been
> rollbacked enough times to reach DLQ removes the messages but does not update
> message count. Better would be if retryMessages didn't remove messages that
> have not been sent to DLQ, but as it is now it is reported to be 1000
> messages on the queue but it is empty when browsing it.
> resetMessageCounter() does not fix anything and removeAllMessages() reports 0
> and still 1000 messages in message count (no change to the other fields
> either).
> Of course, this is not done that often and service is still running fine, so
> it is a minor problem.
>
> Edit: Fixed minor spelling and grammar mistakes. English is not my native
> language so there are probably more there, please fix them as you spot them.
