Description

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.
