That likely means that initializing the AWT toolkit is interfering
with this functionality.<br>
<br>
I presume you are using a very recent ea build of JavaFX 22. What
version of JDK are you using?<br>

<p>Well, that is going to be a fun one to debug ... In my
application I check for a headless environment with
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices().
If you call that one before you initialize your application, the
preferences detection does no longer update. So if you augment
your PlatformPreferencesChangedTest application with this main
method, it no longer works. Also, it throws another exception
when clicking on the fail button.<br>

If you have the chance, maybe you could run the
PlatformPreferencesChangedTest application:

That might rule out that the differences we're seeing have anything to
do with the way we're using the API.
