Bug: https://bugs.openjdk.java.net/browse/JDK-8145901
Webrev: http://cr.openjdk.java.net/~prr/8145901/

As per the evaluation in the bug this is an issue with the
device scale being applied to the kerning adjustments made
by the layout engine.

The fix builds cleanly in JPRT and has been tested with the
the JCK test in the bug report.
I also did "on-screen" testing of various scripts and did not
see any problems.
