So I did this PR by reverting JDK-8292716 and JDK-8292763 fixes, applying this move cleanly, and then reapplying the first two cleanly. Therefore both JDK-8292716 and JDK-8292763 still effectively remain in 17u-dev. See commit history for individual commits. This also makes sure we do not miss anything in backports.
