Hello,
I'm getting a really unusual (and spectacular) crash when JBoss 5 Beta 2 starts
up. This is a naked/unmodified install from the zip file and nothing running
on it except what came packaged.
I have successfully taken 4.0.5 and 4.2.0 out of the box and they ran just fine
with no issues

Gracias, Jaikiran.
What a bummer! I hope this gets fixed in a patch soon. My new application

I think we're looking at the same problem from different angles. One desired
