I'm still seeing "org.jboss.aop.NotFoundInDispatcherException: Object with oid: -2147471496 was not found in the Dispatcher" in my logs, it seems to happen after a couple of days uptime, and as far as I can tell, always when trying to create a new Session from an existing Connection object. Can you shed some light onto what the exception actually means so I can see if it is something I am doing wrong in my code?
