> Key: AMQ-6986
> URL: https://issues.apache.org/jira/browse/AMQ-6986
> Project: ActiveMQ
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 5.15.3
> Reporter: Davide Del Grande
> Priority: Major
>
> With KahaDB, empty queues (0 pending messages) "survive" broker restarts.
> Instead when using JDBC persistence, they just disappear (while queues with
> pending messages work just fine).
>
> It also seems that Topics are deleted (not sure about this).
>
> This is pretty annoying because, at least in my use-case, a monitoring system
> periodically polls queues to see if they are empty or not - and it fails if
> it cannot find the queues that it was polling before broker restart.
> And for topics, this can break the application, too.
>
> I can't understand if this is per-design (is it documented?) or I'm facing
> some bugs.
