I have a class that extends javafx.scene.control.Control. In the Control class there's a static block that calls another static block in PlatformImpl that causes an IllegalStateException.

Because it's a static block it will always (you never know exactly when actually) be executed before the toolkit can be started. This makes it impossible to run any javafx application.

Tested on 8b113 & 8b106
