Build success!

[Martijn Verburg]

Hi all,

In an attempt to be the most annoying person on build-dev in June (do you
hand out prizes, because I'm totally winning).  I'm now at the "error:
comparison of array 'rasterP->sppsm.offsets' not equal to a null pointer is
always true" bug aka https://bugs.openjdk.java.net/browse/JDK-8080993

The workaround suggested in that bug does the trick and I have jdk9
building once more.  Thnaks all!

Cheers,
Martijn
