JavaFX: “Toolkit” not initialized when trying to play an mp3 file through MediaPlayer class

by

JavaFX performs “hidden” initialization on start. Running MediaPlayer doesn’t trigger initialization.

The easiest ways to trigger it are:

  • have Application.launch() executed
  • have Application based program being run from jar packaged by fx ant tasks (e.g. built from Netbeans JavaFX project)
  • have JFXPanel started
  • call Platform.startup(Runnable) (Java 9+)
