[API Review] FXMLLoader's protected fields

[Martin Sladecek]

Hello,

FXMLLoader contains a number of protected (non-final) fields that were 
made 'protected' probably just by accident. I'm going to make these 
fields private. If there's somebody who is working on a FXMLLoader 
subclass, let me know if you need some of the fields, so we could turn 
them into getters or something.

Here's the list of the fields:

protected Object controller;
protected Object root;
protected ResourceBundle resources;
protected URL location;


Thanks,
-Martin
