This is nearly the same as bug no. 4060907, but still reproducible in JDK1.2beta4!

The attached program does the following:
1. create a server socket on port 8003
2. 'exec' Windows-Notepad
3. close the server socket
4. try to create the server socket again

On (4.) I get the following error message:
java.net.BindException: Address in use: bind

If I do not exec Notepad or if I do a waitFor(Notepad), it works fine.

The test program:
--------------------------------------------------
import java.io.*;
import java.net.*;
import java.util.*;

public class TestBind
{
    public static void main (String[] args)
    {
        ServerSocket mySocket;

        try
        {
            Properties prop = System.getProperties();
            String javaver = prop.getProperty("java.version");
            if (javaver != null)
                System.err.println("java version: "+javaver);
            else
                System.err.println("java.version: not found");
            // create socket
            System.err.println("create serverSocket");
            mySocket = new ServerSocket(8003);

            // exec notepad
            String[] execcmd = new String[2];
            execcmd[0] = "c:\\winnt\\system32\\notepad.exe";
            execcmd[1] = "c:\\tmp\\test.html";


            // execute the command
            System.err.println("start exec");
            Process notepad = Runtime.getRuntime().exec (execcmd);
            //System.err.println("waiting for end of notepad");
            //notepad.waitFor();

            // close socket
            System.err.println("close serverSocket");
            mySocket.close();

            // open socket again
            System.err.println("open serverSocket again");
            mySocket = new ServerSocket(8003);
            
        }
        catch (IOException e)
        {
            System.err.println(e);
        }
        /*catch (InterruptedException e)
        {
            System.err.println(e);
        }*/

        System.exit(0);
    }
}
