One thing that i know that has changed in JBoss-5 related to logging is that the server.log appender is now having a default threshold. Earlier there was no threshold so any "level" of logs including TRACE level would be logged into that. But in JBoss-5.0 you should pass the threshold log level through the jboss.server.log.threshold param. Ex: -Djboss.server.log.threshold=TRACE So if you are logging at TRACE level then you might have to pass this. And that's the reason why i asked about logging :) Other than that, you could attach a debugger and add breakpoints and run JBoss in debug mode to see the flow of control. So far, nothing seems to be odd from the logs. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4207419#...
