Richard Huddleston commented on ELY-1570:
-----------------------------------------

Thanks for the super quick response.  Agreed.

JConsole and JVisualVM have jboss-client.jar as part of the classpath which turns into a "System" classLoader of type "AppClassLoader".  But JMC only lets you add " jboss-client.jar " as part of the boot classpath, which results in any classes loaded having a null classloader.  I can't find a way to make JMC (which is based on Eclipse) let me add jboss-client.jar  as part of the class-path.
