We need patches both Bug1435 and 1659 to fix JDK-8017773 .

Patch of Bug1435 is not merged to OpenJDK (jdk7/8/9) yet.
It has been merged to JDK which is bundled in IcedTea7.

So I think that I want to push patch of Bug1659 to IcedTea7 and IcedTea7-2.4 first.
After that, I will send request to java-2d mailing list to merge them as JDK-8017773.


Thanks,

Yasumasa


P.S. My customer uses RHEL.
      So my goal is that Red Hat releases errata to fix this issue :-)
