java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)

Java Application started as Service under Win NT/2000 dies if user logs off
see bug#4323062

This is a regression bug. The application worked fine in JDK1.3.1-b24
if we pass -Xrs flag as a command line option to the JVM. But it had
broken in JDK1.3.1_01.


Using ServiceInstaller 1.1 (http://www.kcmultimedia.com/smaster) install a
simple Java app as a service that outputs some trivial data to a file every
10 seconds.

Here's the simple demo service :

import java.io.*;
import java.util.*;


public class Test2
{
    public static void main(String[] args)
    {

        Date now;
        PrintWriter out;

        try{

            

            while(true){

                now = new Date();
                out = new PrintWriter(new FileWriter("test2.out",true), true);
                out.println(now.toString());
                out.close();

                Thread.sleep(10000);

            }

        }catch(Exception e){

            System.out.println(e.toString());

        }
    }
}

With JDK1.3.1:
-------------------------

Start the service from the Control Panel|Services Applet, and check the
contents of the file test2.out, which should append a line showing the
date and time each 10 sec.

Log off, and log back in.

Although NT thinks the service is still running, it is not. You will see
that lines are no longer appended to the file.

If you pass -Xrs command-line option to the JVM, then the application works fine(Bug ID: 4323062).


With JDK1.3.1_01:
------------------------
Please pass -Xrs flag as an command line option to the JVM.

Start the service from the Control Panel|Services Applet, and check the
contents of the file test2.out, which should append a line showing the
date and time each 10 sec.

Log off, and log back in.

Although NT thinks the service is still running, it is not. You will see
that lines are no longer appended to the file.

If you do not pass -Xrs flag as a command line option to the JVM, then
the application works fine.
