This fix was tested with Mach5 Tier[1-8] when it was part of:
https://github.com/openjdk/jdk/pull/13519

and is also being tested with Mach5 Tier[1-8] combined with
the fix from JDK-8307067 and what remains in JDK-8305670.

I suppose there isn't any way to give @robehn credit for his reviews when this
fix was part of https://github.com/openjdk/jdk/pull/13519.
