Getting javax.management.InstanceNotFoundException: java.lang:type=Threading is not registered in 4.3.0.GA_CP09

Even after applying the following JAVA_OPTS in the "run.conf" we get the error in EAP4.3 GA cp09 but the same program works fine in EAP5.1
As mentioned in : https://issues.jboss.org/browse/JBAS-2427

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9900 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

JAVA_OPTS="$JAVA_OPTS -Djboss.platform.mbeanserver -Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl -Dsun.lang.ClassLoader.allowArraySyntax=true"

Need a patch for EAP4.3 GA CP09 as the same error is not being thrown in EAP5.1

OUTPUT in EAP4.3 GA CP09 as following:
$ java ShowMbeans localhost 9900 java.lang:type=Threading ThreadCount
javax.management.InstanceNotFoundException: java.lang:type=Threading is not registered.

OUTPUT in EAP5.1 as following:
$ java ShowMbeans localhost 9900 java.lang:type=Threading ThreadCount

Value of : java.lang:type=Threading,ThreadCount : 58
