How do I get rid of Java child processes when my Java app exits/crashes?

Question

I launch a child process in Java as follows:

final String[] cmd = {\"\"};
Process process = Runtime.getRuntime().exec(cmd);
         


        

Answer 1

I worked it out myself already. I add a shutdown hook, as follows:

final String[] cmd = {""};
final Process process = Runtime.getRuntime().exec(cmd);
Runnable runnable = new Runnable() {
    public void run() {
        process.destroy();
    }
};
Runtime.getRuntime().addShutdownHook(new Thread(runnable));
