The latest version of the fix looks better. There is only one remaining problem
that I see: If an application calls `Platform.exit()` while in full-screen mode
the following exception will be thrown and printed to the console:
Exception in thread "JavaFX Application Thread" java.lang.NullPointerException:
Cannot invoke "com.sun.glass.ui.Application.staticScreen_getScreens()" because
the return value of "com.sun.glass.ui.Application.GetApplication()" is null
at
javafx.graphics@18-internal/com.sun.glass.ui.Screen.initScreens(Screen.java:410)
at
javafx.graphics@18-internal/com.sun.glass.ui.Screen.notifySettingsChanged(Screen.java:379)
This will happen regardless of whether full-screen was entered via the green
full-screen button, or by a call to `Stage::setFullScreen(true)`. The easiest
way to reproduce this is with the `HelloFullscreen` test program, which is in
`apps/toys/Hello`:
1. Run `java hello.HelloFullscreen`
2. Press the `Exit` button.
If instead you either press the `Close` button (which hides the stage) or use
the red X in the window decoration, the application closes without throwing the
exception.
