When ORB.string_to_object is invoked with a valid corbaloc URL, the
J2SE 1.4 ORB is internally sending a GIOP LocateRequest message. If the
LocateRequest fails (e.g., if the server is not currently running),
string_to_object raises INV_OBJREF.

Ideally, the ORB should not be sending a LocateRequest message from
string_to_object. Instead, the ORB should use late binding,
i.e., don't bind until the first request is made on the object
reference.

  To reproduce the INV_OBJREF exception and demonstrate that
string_to_object is making a remote invocation, use the
following program:

public class Bug
{
    public static void
    main(String[] args)
    {
        org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, null);
        final String URL = "corbaloc:iiop:localhost:5000/NameService";
        try
        {
            org.omg.CORBA.Object obj = orb.string_to_object(URL);
            System.out.println("OK");
        }
        catch(org.omg.CORBA.INV_OBJREF ex)
        {
            System.out.println("Caught INV_OBJREF!");
            ex.printStackTrace();
        }
    }
}

Then follow these steps:

1) Start tnameserv on port 5000:

  tnameserv -ORBInitialPort 5000

2) In another window, run the example program (you should get "OK")

3) Now stop tnameserv, and run the example again. You should
   get the following output:
