The following exception are thrown when asking the MBean server for the classname implementing "jboss.jsr77:j2eeType=WebModule,name=MyWar.war,J2EEServer=default".

It should be a legal call. Why are the code clearly states it's illegal?

java.lang.IllegalStateException: JBAS019905: Should not get called

The error can easily be triggered by using JConsole to browse the same MBean.
