jmx-console problem with jetty / Java2ClassLoadingCompliance

SourceForge Submitter: mmoulton .
I recently configured JBoss-3.2.3RC1-jetty-4.2.14, after
getting everything running for my environment I am
getting a "java.lang.IllegalStateException: No 'jboss'
MBeanServer found!" when I try to access the jmx-console.
After a bunch of troubleshooting I have narrowed the
problem down to 1 area.

For some apps I run, I need the
Java2ClassLoadingCompliance attribute in jetty's jboss-
service.xml set to false. To do this I unpacked the .sar as
it is not unpacked by default in this build. I then made my
change to the jboss-service.xml where appropriate. After I
make this change I am unable to access the jmx-console;
while prior to the change, everything works fine.

I narrowed the problem down to a jboss-jmx.jar located in
the jmx-console.war. When I removed this jar everything
seems to work fine.
