Determine if jboss.platform.mbeanserver system property still needs to be passed inorder for JON to properly manage the JVM instance associated with the EAP5 instance.
Tested with EAP5.2 and Oracle JDK7: "-Djboss.platform.mbeanserver=true" still required. I was expecting that as this system property only tells JBoss to use the VM MBean server instead of creating a new one to install its services. Does not look like related to JDK level.
