I was editing the configuration of my JBoss test installation yesterday and it no longer boots. I backed out the four changes ( adding an SSL connector/mbean and changing the hostname to the actual computer name )).

That didn't solve the problem. I'm getting a ton of persistence related errors and when I try to access the web-console all I get is a white window. It connects, but fails to serve content.

Here's the first errors in the server log, all total there are dozens of related errors.
