LenientParseTest.java was brought in as part of [JDK-8327640](https://bugs.openjdk.org/browse/JDK-8327640), which was a large patch and required a CSR, thus including it in this PR is unlikely to be approved by the maintainers. I would drop this PR.

If you do want to get this fix done, I'd file a new JBS issue against 21u and write a new test for just this fix.
