>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.5.0, 5.6.0
>            Reporter: Torsten Mielke
>              Labels: SessionPool, activemq-web-console,
>             Fix For: 5.6.0
>
>
> In activemq.web project, SessionPool.returnSession() does not check if the session is still open. As long as the session isn't null, its returned back to the pool.
> At least one customer reported a problem when using the web console for browsing a queue, where the session was already closed.

> Not sure what triggered the closure of the session, however once it is closed it should not be returned to the pool but be discarded. If its not discarded, then the pool will always return the closed session and any invocations on the session return an exception. Restarting the broker is the only remedy.
