I've done 8365389 for [11u](https://github.com/openjdk/jdk11u/pull/105) and [8u](https://github.com/openjdk/jdk8u/pull/79). Testing would be welcome. If we can get those in tomorrow, they will make it before freeze.

The other changes hasn't been pushed to trunk yet, but it is only further cleanup and a test. 8365389 is the fix.
