JBoss fails to start with ENABLE_MODELER set to true

Issue

• We're trying to run the mod_cluster load demo app on EAP 6. This requires org.apache.tomcat.util.ENABLE_MODELER to be set to true.
• With org.apache.tomcat.util.ENABLE_MODELER set to true, EAP 6 fails to start properly with the following errors:
