[procrun] net stop command fails, when the Java application exits by using System#exit().
-----------------------------------------------------------------------------------------

                 Key: DAEMON-103
                 URL: https://issues.apache.org/jira/browse/DAEMON-103
             Project: Commons Daemon
          Issue Type: Bug
    Affects Versions: Nightly Builds
         Environment: Windows XP (32bit)
            Reporter: Hikaru Sato


net stop command output a following message and failed.

C:\temp>net stop servicename
System error 109 has occurred.

The pipe has been ended.

I made a following test case. when the test case exited by using return, net stop command worked. But when it exited by using  System#exit(), it failed.

=== FROM HERE TEST CASE.

import java.net.ServerSocket;
import java.net.Socket;

public class TestService extends Thread {
    private static final int PORT = 8980;
    private static ServerSocket socket;

    public static void main(String[] args) throws Exception {
        if (args[0].equals("start")) {
            startService();
        } else if (args[0].equals("stop")) {
            stopService();
        } else {
            ;
        }
    }

    private static void startService() throws Exception {
        socket = new ServerSocket(PORT);
        TestService thread = new TestService();
        thread.start();
        thread.join();
    }

    private static void stopService() {
        try {
            Socket sock = new Socket("127.0.0.1", PORT);
        } catch (Exception e) {
        }

    }

    public void run() {
        try {
            while (true) {
                Socket cli = socket.accept();
                cli.close();
                System.exit(0); // net stop command fails.
//                return;// net stop command works well.
            }

        } catch (Throwable e) {
            ;
        }

    }

}

[jira] Closed: (DAEMON-103) [procrun] net stop command fails, when the Java application exits by using System#exit().

["Mladen Turk (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DAEMON-103?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mladen Turk closed DAEMON-103.
------------------------------

    Resolution: Won't Fix

If using jvm.dll the main() method becomes the part of the service process.
Actually it is called from a separate thread and procrun waits until it terminates
(main() method returns)
If you call the System.exit it will cause service exit without a chance to
report to the service manager that the application exited cleanly.

Solution is to use the exit hook inside the main method, and
that is what daemon java code does.
