Timothy Bish closed AMQ-3111.
-----------------------------
Resolution: Cannot Reproduce
tested against 5.9.0 and queue counts are not showing negative numbers in the
tests.
> Negative Pending Message Count
> ------------------------------
>
> Key: AMQ-3111
> URL: https://issues.apache.org/jira/browse/AMQ-3111
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.4.0
> Environment: Windows XP, ActiveMQ 5.4.0
> Reporter: ashwini kuntamukkala
> Attachments:
> FailingMessageRedeliveredDespiteBeingMovedToExceptionQueue.java
>
>
> When a queue connection redelivery policy's max redelivery time is set to
> -1, and the bad message which is failing constantly needs to be moved to
> exception queue manually (JMX JConsole, ActiveMQ WebConsole), then dequeue is
> accounted twice for the same message.
> Say at time T0 queue is empty
> queue has a registered listener
> T1 => message gets put on the queue => enqueue = 1, dequeue = 0, pending = 1
> T2 .. T3 .. T4..T5 this message is constantly failing because of some runtime
> exception
> Using ActiveMQ webconsole, we move this to exception queue...and have logic
> in the consumer to commit the session if this is a redelivered message that
> does not exist on the queue, Refer AMQ 3110
> Then,
> at T6
> enqueue count = 1, dequeue count = 2, pending count = -1
> Attached is the unit test showing this issue.
> Please refer the log pasted below.

> -----
> Please run the attached Junit test and see this issue. Since AMQ 3110 is
> still unresolved, the only way we could get rid of the bad message being
> redelivered despite having been moved to an exception queue was by checking
> the redelivery counter and if the message was still on the queue, if not,
> then we acknowledge the session so subsequent messages can be processed.
> Thank you,
