Hello,
Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8149115

webrev: http://cr.openjdk.java.net/~ssadetsky/8149115/webrev.00/

Currently the hidpi support on linux only reads GDK_SCALE environment 
variable to get the native scale. Although, Gnome3 and Unity DE use 
own settings to control the interface scale. The fix adds possibility 
to read those settings to make java apps hidpi scale similar to the 
native apps. Currently only integer scale values are supported. If 
native scale is not an integer value it is rounded to the nearest 
integer.
  systemScale.c
   Should the while loop have a break statement in the 
getDesktopScale(...) method?

  Thanks,
  Alexandr.
