No, unfortunately not: _"Switching from 11 to 17 seems to mend the (unknown underlying) issue for the time being."_
A test build using the same JDK as pre-installed on GitHub-hosted runners on my local machine did not fail either.

No. JDK 17 is archived and it uses JDK 8 to build jtreg within a single-file workflow definition:

- https://github.com/openjdk/jdk17/blob/master/.github/workflows/submit.yml#L88

A backport to JDK 21 makes sense.
