Mario Siegenthaler updated AMQ-2166:
------------------------------------
Attachment: AMQ-2166.patch
Removes the session from the list held by the connection as soon as the session
is closed.
I also synchronized access to the session-collection since there might be more
than one thread calling #createSession().
Apply to activemq-ra.

> Key: AMQ-2166
> URL: https://issues.apache.org/activemq/browse/AMQ-2166
> Project: ActiveMQ
> Issue Type: Bug
> Components: JCA Container
> Affects Versions: 4.1.0, 4.1.1, 4.1.2, 5.0.0, 5.1.0, 5.2.0
> Reporter: Mario Siegenthaler
> Attachments: AMQ-2166.patch
>
> Original Estimate: 10 minutes
> Remaining Estimate: 10 minutes
>
> The ActiveMQ JCA Resource Adapter leaks about 1Kb of memory when opening and
> closing sessions on the same connection. As soon as the connection is closed
> this memory is released, but it's a common use case to keep the connection
> for a very long time (ie aquire at startup and relase at shutdown).
> The leak happens because the ManagedConnectionProxy holds a list of sessions
> that have been openend, but there's no code that removes a closed session
> from the list.
