Missing class declarations referenced from tests

[Nir Lisker]

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?
