There seems to be a problem with this PR. It shows commits [not part of this PR](https://github.com/openjdk/jdk8u-dev/pull/158/commits/f81f0a51f183d38248fdee4242f012257076d6ab), but others (e.g. #135). The bot is also not happy about it. Before this can get properly reviewed, this would need some fixup.

This doesn't look right. It's part of #135. See: https://github.com/openjdk/jdk8u-dev/pull/135/files#diff-840578f66556c33204f36e83d8c5a6b6b91c0280ffdbbea6121847a5b6b1afe7R259
