How to quit the J2ME emulator when running from a batch?

Question

I am launching the J2me emulator from a batch file in order to run unit tests (J2meUnit). I am using "emulator.exe -classpath ... -Xdevice:mediaControlSkin -Xdomain@trusted com.mydomain.TestMyMidlet".
This works fine, and some of the tests even pass (;-)) but after the last one the emulator sits there waiting for me to shut it down, which would get a little tiresome at 4.00am every morning when the rest of the automated unit tests run ;-) How should I terminate it please? I tried to call destroyApp(true) after the last test but got "java.lang.SecurityException: Application not authorized to access the restricted API". What am I missing please? Thanks for any ideas...

You can extend j2meunit.midletui.TestRunner (which you are probably already doing),
copy-and-paste the start method from the source package, then change the end to look like this:
                              System.out.println("Exception while running test: " + e);
                         e.printStackTrace();
// start change
               finally
                         notifyDestroyed();
// end change
          }.start();
     }In other words, when all the tests are done, notify the application manager that you're all done. (destroyApp is what the app manager calls, notifyDestroyed is what you call)
On the same topic (risking modestly hijacking the thread here) I'd like to ask if anyone knows how to just run some class inside a J2ME VM without having to pop up the UI.
I know there is a j2meunit.textui.TestRunner, but I haven't figured out any way to get a command-line KVM without an UI at all. AWT throws exceptions when no X server is running (or you unset $DISPLAY). Of course, everything runs fine (except that you can't specify an exit code, which gives you some more hoops to jump through with ant), but I don't think an unit test should need an X server running / should pop up a window for half a second.
