See https://github.com/openjdk/jdk8u/pull/84 for a proof of concept as to what is needed to get macosx building in GHA again.

The last remaining piece for a macOS x build seems to be something like this now: https://github.com/openjdk/jdk8u/pull/84/commits/bacf30605ae1b8eb21010aa8d96b3a21e73ecccf. This is not needed in JDK 11 due to JNF being removed there: https://bugs.openjdk.org/browse/JDK-8257852 and https://bugs.openjdk.org/browse/JDK-8257988
