I have enabled jboss org.jboss.jmx.connector.invoker.AuthorizationInterceptor in the jmx-invoker-service.xml file and when invoking the mbean to get multiple attributes in a single call, I get this exception: IllegalArgumentException("Opname type not recognized"); If you get an mbean connection from the RMIAdaptor and issue: MBeanServerConnection.getAttributes(objectName,new String[]{"name","state","running"}); It will toss the exception. I can't find a workaround. Is there another AuthorizationInterceptor to use. Maybe this is a bug. I am most likely going to have to write my own. Thanks.
