Bug Description:
  ClassCastException in
  com.sun.corba.se.internal.iiop.ShutdownUtilDelegate using code described
  in http://java.sun.com/j2se/1.4/docs/guide/rmi-iiop/interop.html while
  accessing a remote EJB using RMI-IIOP using J2EE-SDK 1.3.1 and
  JDK1.4.0/1.4.1

  The bug occurs, if prior to the operation on the home-interface the
  CORBA NameService is resolved - you can illustrate the problem by using
  attached test.sh script.

Steps to Reproduce (be specific):
  1. Follow the steps described in "Creating a Java RMI-IIOP client
     application" in
     http://java.sun.com/j2se/1.4/docs/guide/rmi-iiop/interop.html
  2. While running the client, the following exception occurs (stack trace
     from another test client)
     Exception in thread "main" java.lang.ClassCastException
    	at
com.sun.corba.se.internal.iiop.ShutdownUtilDelegate.isLocal(ShutdownUtilDelegate.java:39)
    	at javax.rmi.CORBA.Util.isLocal(Util.java:262)
    	at
com.pironet.pb.security.server._UserHome_Stub.findByPrimaryKey(Unknown Source)

  A workaround may be patching the ShutdownUtilDelegate class by modifying
  the isLocal method as follows (adding the "instanceof" test):
    public boolean isLocal(javax.rmi.CORBA.Stub stub) throws RemoteException {
        try {
        org.omg.CORBA.portable.Delegate delegate = stub._get_delegate();
        if (!(delegate instanceof ClientSubcontract)) return false;
        return ((ClientSubcontract)delegate).useLocalInvocation( stub );
        } catch (SystemException e) {
            throw javax.rmi.CORBA.Util.mapSystemException(e);
        }
    }

Not carefully test the workaround - but it works for now.
