You may follow it thusly:
1. a client hold on to a JmsSession (org.jboss.jms.ra)
2. Invokes close on it.
3. JmsSession uses the JmsManagedConnection to send a CONNECTION_CLOSED
connection event.
4. JmsManagedConnection (in sendEvent) will send a CONNECTION_CLOSED to
all its registered ConnectionEventListeners.
5. The JBoss pool manager will detect the CONNECTION_CLOSED and invoke
cleanup on the ManagedConnection (MC) (and perhaps som TX stuff) and
return it to the pool.
(If the pool management want to destroy managed connections in the pool
it may do so, by invoking destroy() in the MC. The JmsSession or the
JmsMC may also throw a connection event exception, in wich case the pool
should destroy the MC.
I do not really know if this helps in you solving the problem.
