These tests

java/rmi/activation/rmidViaInheritedChannel/RmidViaInheritedChannel.java
java/rmi/activation/rmidViaInheritedChannel/InheritedChannelNotServerSocket.java 

fail with a NullPointerException when attempting to dereference the rmid instance variable. This is due to this structure

        RMID rmid = null;
        try {
            System.err.println("export callback object and bind in registry");

            // bind to the registry (code omitted)

            System.err.println("start rmid with inherited channel");
            rmid = RMID.createRMID( ... );

            // more code omitted
        } finally {
            if (obj != null) {
                UnicastRemoteObject.unexportObject(obj, true);
            }
            rmid.cleanup(); // <--- line where the exception occurs
        }

where the error actually occurs between the print statements.
