A MethodCall containing a method from a base class fails to invoke correctly on an instance of a derived class.

Sample error message: 2005-02-18 08:59:21,551 ERROR [org.jgroups.blocks.MethodCall] found no method called _receiveRemoteNotification in class org.jboss.ha.singleton.HASingletonController with (javax.management.AttributeChangeNotification) formal parameters .

In the example above, the HASingletonController class does not declare _receiveRemoteNotification(), but one of its ancestors does.
