I added -agentlib:hprof to standalone.conf JAVA_OPTS, and start the server, and failed with the following errors.  I then added the classes reported missing to sun.jdk module, and even made it a global module in standalone.xml, to no avail.

Looks like we need these classes at jvm init phase, but jboss modules' boot loader doesn't include them, maybe for performance reason.  Any ideas?
