> I called JMXConnectorServerFactory.newJMXConnectorServer to instantiate a RMIConnectorServer and registered it in the jboss mbean server. (Inside the Jboss AS 4.0.1).
> The resulting class javax.management.remote.rmi.RMIConnectorServer does not return a classloader in the call RMIConnectorServer.class.getClassLoader(), which is legal according to the jdk api documentation (see java.lang.Class#getClassLoader).
> Unfortunatelly the isInstanceOf method of org.jboss.mx.server.MBeanServerImpl does not take this into account. Thus I get a NullPointerException if I call isInstanceOf on that particular MBean.
