@dholmes-ora - Please re-review this PR now that two pieces have been refactored
out into JDK-8307067 and JDK-830-7068.

@robehn - Any chance you are around for a re-review?
@coleenp - Any chance you can review this part since you already reviewed JDK-8307067?
@apangin - You looked at this fix when it was part of https://github.com/openjdk/jdk/pull/13519. Any chance you can take another look?
