|Marc: We might want to consider doing some sort of
|"known issues" kind of thing with JBoss_final2.0? I'd
|be happy to contribute what I've uncovered so far..
|which has been minimal, a tribute to the work done
|thus far.
yes this is a good idea, I want to do a new binary release so please let us
know what you have... bugzilla + mail
thanks
