@dholmes-ora @aivanov-jdk @prrace I can see that there are duplicated issues on this topic, and that regression is easy without proper testing, but is that a reason to not merge this kind of code? If new regressions occurs, then chances are big that someone will notice them, and push a new fix for it.

Yes, buildroot is a bit behind upstream JDK, but at least there we will see it. https://github.com/buildroot/buildroot/commit/3dd73c30d387b235589275bad729e66619d062c3 Other distributions might also be interested.

Are there actions needed on my side? Because that is not clear out of the reviews.
