I'm running JBoss 4.2.2.GA (just the standard distribution, no other applications deployed) with Sun JDK1.6.0_10. The platform MBean server is enabled with JAVA_OPTS="-Dcom.sun.management.jmxremote -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" in the run.conf file in the bin directory., as described in the Wiki. JConsole does show the JBoss MBeans in the console's MBean Tab, but all other Tabs (Memory, Threads, ..etc) are greyed out and unavailable. When I use the JBoss MBean server, removing the jboss.platform.mbeanserver option, those tabs are available, but of course the JBoss MBeans are not shown. JRockit1.6 shows the same behaviour.
