Exception in thread "LWJGL Application" java.lang.NullPointerException

[StefanH-AT]

Last commit was 4 years ago but I hope someone knows what's wrong.

I get this stacktrace every single time when running an LwjglFxApplication. (I tried the example code, still doesn't work)

Exception in thread "LWJGL Application" java.lang.NullPointerException
	at com.badlogic.gdx.backends.lwjgl.LwjglGraphics.initiateGLInstances(LwjglGraphics.java:378)
	at com.badlogic.gdx.backends.lwjgl.LwjglFXGraphics.setupDisplay(LwjglFXGraphics.java:88)
	at com.badlogic.gdx.backends.lwjgl.LwjglFXApplication.mainLoop(LwjglFXApplication.java:65)
	at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:126)

The exception causes libGDX to crash, the JavaFX Stage still works though
