I would like to raise a new bug report. The J2SE 1.5 ORB exhibits 
behavior that was not present in J2SE 1.4.x. In particular it throws the 
following exception when a server sends a CLOSE_CONNECTION message and 
closes the socket:
=========================
 Warning Message seen :

Although the message is harmless, the ORB is not supposed to treat this as 
an error. Instead it should silently allow the socket to be closed. J2SE 
1.4.x does this and we would like to see the correct behaviour reinstated 
in J2SE 1.5

 We have reproduced the problem in the following system :
 SunOS dts-sb-1 5.9 Generic_112233-12 sun4u sparc SUNW,Sun-Blade-1000

 Follow the steps to reproduce the problem :
1. Download and install WLS 8.1, platform should not matter, from commerce.bea.com
2. Start the examples server.
3. Using the console change the IIOP idle connection timeout to 5s, you can reach this via Servers->examplesServer->Protocols->IIOP
4. Compile and run the below test program under j2se 1.5.0_x

 Test Java Program :

import java.util.Hashtable;
import javax.naming.*;

public class CloseClientTest {
  public static void main(String args[]) throws Exception {
    Hashtable h = new Hashtable();
    h.put(Context.SECURITY_PRINCIPAL, "system");
    h.put(Context.SECURITY_CREDENTIALS, "ejb2come");
    h.put(Context.PROVIDER_URL, args[0]);
    h.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
    InitialContext ic = new InitialContext(h);
    ic.lookup("weblogic/management");
    System.out.println("Connected to " + args[0] + " sleeping ...");
    Thread.sleep(10000);
  }
}

 Command to execute :
    java -cp . CloseClientTest iiop://localhost:7001

 Result :
   Clean run with j2se 1.4.2_x and warning Messages are seen as mentioned above with j2se 1.5.0_x for the above test program.
