It looks like this PR is also trying to bring in JDK-8291637 without its associated test case.

I would suggest opening a separate PR for that backport and making this one dependent on it instead. This change should then be close to clean.

Thanks @gnu-andrew for reviewing this PR.
I created backport #466 and made #453 dependent on the new PR #466 in accordance with the backport order in JDK11U.
