Just to clarify... when I said... "tfennelly" wrote : The handleCloseSession method returns the session to the "free" pool before releasing it's resources. Is that a potential bug? ... what I meant was that this seems like a bug to me (JmsSession.releaseResources aside), because it seems to be happening at the wrong time. Shouldn't the resources be released/cleaned-up before the session is returned to the "free" pool? Shouldn't returning it to the pool be the last step in the process.
