[問題] java呼叫外部程式會當掉

[starskgb (Metal)]

只要用socket程式去call外部程式，外部程式就會當掉
socket server程式如下
class test {
           public static void main(String args[]) throws Exception
              {
                 int serverPort = 80;
                 ServerSocket welcomeSocket = new ServerSocket(serverPort);
                 System.out.println("Server STARTed!!");
                 int i;
                 i = 0;
                 while(true) {
                    Socket connectionSocket = welcomeSocket.accept();
                    i++;
                    String s = Integer.toString(i);
                    Runtime t = Runtime.getRuntime();
                    Process pr=t.exec("D://vstream/run.bat");
                 }
              }

}
bat內容:C:/Progra~1/VideoLAN/VLC/vlc.exe mms://url
但是我把socket的code通通拿掉，只留call bat那兩行，vlc又能正常跑不會當掉
請問這是什麼哪邊出錯Orz
