Hi, I'm looking inside tests/functional and I see that this file
https://github.com/openjdk/jfx/blob/master/tests/functional/animation/javafx/animation/AnimationFunctionalTestBase.java references com.sun.javafx.functions.Function0, but this class can't be found. There is also a commented out section in FloodGame.java in apps referencing this class. This file also has a declaration protected class SimpleTimeline extends Timeline {... which gives an error because Timeline is final. There are more errors there and in its package. What is this package and how does it suppose to work?
