If you like, I'll create a backport issue for 8062808 and point it to the 8176100 backport patch, or I could revert the 8062808-specific code and and do 8062808 separately.

It's ok.  I asked about it more because I was curious why the change was
needed than any intention to require further changes.

I have backports of 8062808 and related issues already downstream that I
intend to include, so I'll just list 8064786 in the commit for 8062808,
so it appears as resolved in OpenJDK 8u, even though the actual fix is
in the earlier commit.
