Ran GHA Sanity Checks, local Tier 1 and 2, and adjusted test directly. Patch is **nearly clean**: since `Reference.refersTo` is not supported, needs minor adjustments.

Taking a closer look at the history, seeing [this](https://github.com/openjdk/jdk11u-dev/pull/869/commits/5ec1e0b8a2a1c3ed745b8ff5fb97b8c0d67354a3) commit when initially backporting the test. Planning to adjust to not use `Reference.refersTo` (which JDK 11 doesn't directly support), rerun local tests and add another commit here.
