I've started a backport of the pre-requisite 8197408 (<https://github.com/jmtd/jdk8u-dev/tree/8197408-jdk8u-dev>) but it's not quite finished. It should slot into this sequence between this PR and its current parent (8239559 / pr/136).

As a reminder to myself, once I raise the PR for 8197408 I should /add 8198833
