URLClassLoader + loadClass + invoke main method on a standalone process? Java

Question

I'm using the following method to invoke a class inside a jar file:

invokeClass("path.to.classfile", new String[] {});

public static void invokeClass(String name, String[] args) throws ClassNotFoundException, NoSuchMethodException, InvocationTargetException, MalformedURLException {
    File f = new File(System.getProperty("user.home") + File.separator + ".myapplication"+File.separator+"myjar.jar");

    URLClassLoader u = new URLClassLoader(new URL[]{f.toURI().toURL()});
    Class c = u.loadClass(name);
      Method m = c.getMethod("main", new Class[] { args.getClass() });
      m.setAccessible(true);
      int mods = m.getModifiers();
      if (m.getReturnType() != void.class || !Modifier.isStatic(mods) || !Modifier.isPublic(mods)) {
        throw new NoSuchMethodException("main");
      }
      try {
        m.invoke(null, new Object[] { args });
      } catch (IllegalAccessException e) {

      }
}

Is it possible to invoke this on a separate process? So the running application and the new invoked application have nothing in common?

Situation: You launch program a (client updater). From client a you launch program b (client)

With the current code, project a AND all instances of project b share the same heap space. I'm trying to achieve a state where all instances of project b are stand-alone and do not care if project A is terminated or not.
