1.4.5.GA is for AS 4.x only. The next release for AS 5 (supposedly 1.4.6.GA) will come soon hopefully. It needs to be tested with AS 5 jars. It should also be noted that the next release requires remoting 2.5.2 at least (currently in AS 5 it is 2.5.1).
Thanks Howard. I will keep an eye out for 1.4.6
P.S. Did anyone get a chance to look at the log I posted to https://jira.jboss.org/jira/browse/JBMESSAGING-1706? I think I may have found the source of this tricky problem (ie. ConnectionStopRequest.serverInvoke)
can i upgrade AS5 to use messaging 1.4.8.SP9 ? Do i also need to upgrade jboss messaging? What version would it require?
