API break in 2.1 JavaFXBuilderFactory

I'm seeing this exception on 2.0.2 with the default constructor - on 2.1
all is fine!

My problem is that to support my tooling on OS-X (2.1) and Windows
(2.0.2 & 2.1) I now have to use reflection to use the none default
constructor making my code look ugly but well if it has to be like this
... .
