A modern programming language that makes developers happier.

I've an existing tornadofx program that was still using `Application` instead of `App`. When I just changed it to the latter, I got an NPE on exit (in `App::stop()`because primaryStage wasn't set. I added to the existing start method `FX.setPrimaryStage` to get past that. I am now getting an NPE in the following lines, which seem to be finding and cleaning up the primary view. I'm starting to suspect "you're doing it wrong". Is my problem that I have a custom `start()` that doesn't call the super? Should I not override start at all and override some other method called by App::start instead? Should I also have overridden stop()? The existing `start()` is needed because the program has to first show a dialog box. It's possible that the user can cancel out, in which case I don't want the stage showing at all, just want to exit.

Overriding `start()` without calling `super.start()` is bound to cause a bunch of problems. There is a lot of critical framework setup expected to happen in there.

Okay, cool. For my next swing I'll try that. Thanks!
