hey List, Since there hasn't been any feedback on this bug yet, I would like to start taking a look at it myself, as it is important for the project I'm working on. I would appreciate any extra developer documentation (UML diagrams would be super) that might be out there that would help me get up to speed quickly on (for starters) the JBossCMP portion of the codebase. I looked on the developer page of the website, but noticed that the developer guide page ( http://main.jboss.org/developers/guide/ ) is empty.
I already have a working cvs HEAD, so I'm really just looking for codebase docs.
