Serversocket.close() not causing accept() to throw IOException

Question

My problem is quiet simple. The follow code does not display the string "accept() failed or interrupted..." on the console. Which I believe is part of the Java specification. The code DOES work on a RedHat Linux machine running Java 1.4.2 and 1.5.0, and it works on a machine with Windows XP and 1.4.2, but it does not work on my SuSE Linux machine with 1.4.2, 1.5.0, or any other 1.4.x jvm I've tried.
What could be wrong?
import java.net.*;
import java.io.*;
class Example5 extends Thread {
  volatile boolean stop = false;
  volatile ServerSocket socket;
  public static void main( String args[] ) throws Exception {
    Example5 thread = new Example5();
   System.out.println( "Starting thread..." );
   thread.start();
   Thread.sleep( 3000 );
   System.out.println( "Asking thread to stop..." );
   thread.stop = true;
   thread.socket.close();
   Thread.sleep( 3000 );
   System.out.println( "Stopping application..." );
   System.exit( 0 );
  public void run() {
    try {
      socket = new ServerSocket(7856);
    } catch ( IOException e ) {
     System.out.println( "Could not create the socket..." );
      return;
    while ( !stop ) {
     System.out.println( "Waiting for connection..." );
      try {
       Socket sock = socket.accept();
      } catch ( IOException e ) {
      System.out.println( "accept() failed or interrupted..." );
   System.out.println( "Thread exiting under request..." );
}

I actually already have a work around, we have set the SoTimeout for our ServerSockets. I also have this problem on regular Socket's as well, and have set their SoTimeout as well.
On a somewhat related note, I'm getting a Hotspot Virtual Machine exception when I try and send some data over one of these connections. Since none of my coworkers have this problem, I assume it has something to do with my computer.
