orb.list_initial_references in JDK 1.4.0 has inappropriate behavior in the following two cases.

Please see the code below.

Case 1: Give
-Dorg.omg.CORBA.ORBInitRef=NameService=corbaloc:iiop:1.2@localhost:<port>/NameService

to the JVM when running the given example code. list_initial_references will try to open port 900 in spite of the port specified, resulting in a COMM_FAILURE minor code 201 (unless 900 is open and available to the user).

The same thing happens when this property is not given.

Case 2: If both the above ORBInitRef property and ORBInitialPort are given, list_initial_references throws an ArrayIndexOutOfBoundsException.

If only ORBInitialPort is given, it works fine.

Code:

import org.omg.CORBA.ORB;

public class ServiceLister
{
    public static void main(String[] args) {
        ORB orb = ORB.init(args, System.getProperties);
        String[] services = orb.list_initial_services();

        if (services == null)
            System.out.println("Services array is null!");
        else
            for (int i = 0; i < services.length; i++)
                System.out.println(services[i]);
    }
}
