> Yes, I looked at these bugs briefly a few days ago along with the fix on the PR you created. While I appreciate the merits of [openjdk/jdk8u at bacf306](https://github.com/openjdk/jdk8u/commit/bacf30605ae1b8eb21010aa8d96b3a21e73ecccf) in getting us further in the build, the final fix does need to be a backport of the JNF removals.

Let's please use the GHA work-around for now until we have all the backports in place to no longer need the JNF workaround. Right now we don't get Mac OS X builds in GHAs at all, which is bad and I'd like to avoid skipping testing on it for much longer before PRs land.
