sun/font/FileFontStrike.java has this code :-
        boolean disableHinting = desc.aaHint != INTVAL_TEXT_ANTIALIAS_OFF &&
                                 fileFont.familyName.startsWith("Amble");

The Amble fonts were licnsed for use by FX a long time ago
and I don't recall that we used them except in FX 1.
Also this logic only mattered when the FX rendering pipeline
was the so-called "Swing" pipeline. Prism obsoleted that and this code which we should remove.
