java version "1.4.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta2-b77)
Java HotSpot(TM) Client VM (build 1.4.0-beta2-b77, mixed mode)


A NullPointerException is thrown when the method
ORB.resolve_initial_references() is called and a non jdk nameserver like
omniNames is used.

1. Exact steps to reproduce the problem:
   - Obtain a copy of OmniORB3 at:
     http://www.uk.research.att.com/omniORB
   - Run OmniORB3 nameserver omniNames:
     omniNames -start 12345 -logdir /tmp
   - Compile and run your example NameClientList.java

2. Java SOURCE CODE that demonstrates the problem:
import java.util.Properties;
import org.omg.CORBA.*;
import org.omg.CosNaming.*;
 
public class NameClientList
{
   public static void main(String args[])
   {
      try {
        Properties props = new Properties();
        props.put("org.omg.CORBA.ORBInitialPort", "12345");
        ORB orb = ORB.init(args, props);
 
        NamingContext nc = NamingContextHelper.narrow(
            orb.resolve_initial_references("NameService"));
 
        BindingListHolder bl = new BindingListHolder();
        BindingIteratorHolder blIt= new BindingIteratorHolder();
        nc.list(1000, bl, blIt);
 
        Binding bindings[] = bl.value;
        if (bindings.length == 0) return;
 
        for (int i=0; i < bindings.length; i++) {
 
            // get the object reference for each binding
            org.omg.CORBA.Object obj = nc.resolve(bindings[i].binding_name);
            String objStr = orb.object_to_string(obj);
            int lastIx = bindings[i].binding_name.length-1;
            // check to see if this is a naming context
            if (bindings[i].binding_type == BindingType.ncontext) {
                System.out.println( "Context: " +
                    bindings[i].binding_name[lastIx].id);
            } else {
                System.out.println("Object: " +
                    bindings[i].binding_name[lastIx].id);
            }
        }
 
       } catch (Exception e) {
            e.printStackTrace(System.err);
       }
   }
}
