[PATCH] Remove usage of private API

[Marco Dinacci]

Hi,

> One other question for you… which JRE did you use when submitting your application?
> I'm trying to determine if you had any of the JavaFX libraries -- 7u4 doesn't bundle JavaFx, but 7u6 does. If you did then that's one less thing for us to check. Otherwise, we will need to scan the native parts of JavaFx to make sure we don't have this problem again later.

I didn't bundle any JavaFX library for sure. We maintain our own 7u
repo that at the time of submission was based on changeset
3ce621d9b988 (jdk7u6-b14).

Best,
Marco
