The backport is clean and tests are green. Maintainers didn't become aware of it because no jdk17u-fix-request flag was set in JBS. As I saw you already added aFix Request comment, I have added both, jdk17u-fix-request and jdk17u-fix-yes. So you can consider it approved and this PR is ready to be integrated.
