JBossAS 4.2.0 had a very large number of component updates compared to any previous 3.x/4.x releases, and it's not easy to get everything right the first time. We'll try to address the issues you mention.
Thank a lot for the input.
What's the status of the documentation right now? JBoss is still an open source project (right?), so you could harness the community here.
But currently I get the impression that the development model somehow "closed" a bit and that help from the outside on this issues is not really wanted.
For example if it was clear for you guys that there will be no installer for 4.2 it would have been nice to tell that to everybody. Instead that seemed to be some internal decision, for which I had to ask about.
We are in the process of updating the docs. You are right, we have been really bad with keeping the docs in synch, we need a more open solution there.
