How can I run a new process, and close the current program in Java?

public class App {
    public static void main(String[] args) {
       Process p = Runtime.getRuntime().exec("java -jar someOtherProgram.jar");
    }
}

This effectively runs my other program. However, this program (App) does not close. It is still running (I can tell because it won't let me kill it in Eclipse). The only way to close this program is by killing the process that corresponds to someOtherProgram.jar.

What I want is for my program, App, to run another Java program. And then kill itself.

Under Windows, I believe you need to use something like...

cmd /B start "" java -jar someOtherProgram.jar

Remember, if your path contains spaces, it will need to be quoted, for example

cmd /B start "" java -jar "path to your/program/someOtherProgram.jar"

You may want to use (on Linux) 

nohup java -jar someOtherProgram.jar &

and in Windows 

start /min java -jar someOtherProgram.jar

or

javaw -jar someOtherProgram.jar

The only way that comes to my head is to use the exit() method. It shuts down itself.

System.exit(0);
