<AWT Dev> [8u] Review request for 8157838 Personalized Windows Font Size is not taken into account in Java8u102

[Phil Race]

 From what I read on the web Windows Vista, 7, and 8, Windows uses this 
setting to scale just
the fonts, but for 8.1 and 10 it is a whole application scale, so 
perhaps rather than just
revert the fix, you can make it OS version dependent ?

Surface Pro devices are not going to be running Vista or 7 .. and I 
expect most are running
Windows 8.1 or later by now.


Of course you will need to find a way to test this hypothesis : probably 
on a windows 10
desktop with 125% scaling to see what happens with the Win L&F.
