To properly propagate the LazyMBeanServer to all jboss mbeans in preRegister, the LazyMBeanServer has to be passed in to the MBeanServerImpl ctor as the outer argument. Its a one line change to do this in LazyMBeanServer.resetToJBossServer to pass the registeredServer: | public static MBeanServer resetToJBossServer(MBeanServer server) | throws Exception | { | MBeanServer coreServer = server; | if( theDelegate != null ) | { | Class[] sig = {String.class, MBeanServer.class, MBeanServerDelegate.class}; | Object[] args = {defaultDomain, registeredServer, theDelegate}; | With this change, I can use twiddle to query the platform mbeans: | [starksm@succubus bin]$ twiddle.sh query 'java.lang:*' | java.lang:type=Compilation | java.lang:type=MemoryManager,name=CodeCacheManager | java.lang:type=GarbageCollector,name=Copy | java.lang:type=MemoryPool,name=Eden Space | java.lang:type=Runtime | java.lang:type=ClassLoading | java.lang:type=MemoryPool,name=Survivor Space | java.lang:type=Threading | java.lang:type=GarbageCollector,name=MarkSweepCompact | java.lang:type=OperatingSystem | java.lang:type=Memory | java.lang:type=MemoryPool,name=Code Cache | java.lang:type=MemoryPool,name=Tenured Gen | java.lang:type=MemoryPool,name=Perm Gen | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130258#...
