Kevin/Jonathan -

Steve's example in the Jira captures perfectly what I was encountering in
Java, and I've been trying to boil it down into a minimal failing example -
reconciling it with what I've experienced in dynamic languages.

Turns out it's about whether or not you extend Application. This leads me
to believe that it's something in Application's classloading that enables
your example to work cleanly.

Try your class out again - with the minor edits I've made below:

public class Example /* extends Application */ {
   public static void main(String[] args) {
       //this is called from a static block in javafx.scene.control.Control
       PlatformImpl.setDefaultPlatformUserAgentStylesheet();

       Application.launch(args);
   }

   /*@Override*/
   public void start(final Stage primaryStage) throws Exception {
   }
}

Cheers,
SR
