Torsten Mielke updated AMQ-3430:
--------------------------------
Attachment: AMQ-3430.patch
Attaching a possible fix including some logging for SessionPool.java
It was necessary to add a public method ActiveMQSession.isClosed() for checking
if a session is closed.
> activemq-web: SessionPool.returnSession() should discard sessions that are
> closed.

> 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.
