Having an app to restart

Hi.

I need that, in some circumstances, my Java application restarts itself.

In a first moment I thought it was as easy as:

            Runtime.getRuntime().exec("/usr/bin/open " + app);
    System.exit(0);

where app contains the full path of the application .app file. Indeed it doesn't work.

After some tryings I discovered that this works:

            File file = File.createTempFile("blueMarine-restart-", ".sh");
            PrintWriter pw = new PrintWriter(new FileWriter(file));
            pw.println("sleep 1");
            pw.println("open " + app);
            pw.close();
            Runtime.getRuntime().exec("/bin/sh " + file.getAbsolutePath());
    System.exit(0);


Basically it looks like the sleep 1 is fundamental - I think because if I try to relaunch the application itself while it's still alive, Mac OS X doesn't nothing.

Can you confirm this? Does somebody have a simpler working code?

Thanks.
