Thanks all! Apology for missing the tests and risk assessment.
I enabled GitHub actions and all tier1 tests passed. (I used `git rebase` and `git push -f` to trigger a run for GitHub actions. Probably should have used `git merge`.)

I updated the "Fix request" comments to include risk assessment and tests on https://bugs.openjdk.org/browse/JDK-8303937, and also added back `jdk11u-fix-request` and `jdk17u-fix-request` tags. Let me know if I missed anything else.
