Starting Jboss with these parameters
./run.sh -Djboss.platform.mbeanserver -Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl

causes twiddle not to display java.lang:* MBeans

[vicky@localhost bin]$ ./twiddle.sh query "java.lang:*"
15:02:14,414 ERROR [Twiddle] Command failure
org.jboss.console.twiddle.command.CommandException: No MBean matches for query: java.lang:*
at org.jboss.console.twiddle.command.MBeanServerCommand.queryMBeans(MBeanServerCommand.java:72)
at org.jboss.console.twiddle.command.QueryCommand.execute(QueryCommand.java:138)
at org.jboss.console.twiddle.Twiddle.main(Twiddle.java:305)

If the Jboss is started as
./run.sh -Djboss.platform.mbeanserver

twiddle query "java.lang:*" works .
