Just today I came from vacation, and when I tried to start server, it shows an alert of 'jboss has encountered a problem...' I don't know what happend in the mid
and in stack trace, with so..many exceptions.. like this
am using jboss 5.1 with jdk 1.6.(am not changed any versions right now)
These are some core classes that it's complaining about. Are you sure the JBoss AS is clean and nothing changed and someone removed or messed up the installation? Try deploying your application to a new and clean JBoss AS instance.
