Adjusts code to avoid a ClassCastException in javac while compiling a non-existent method annotated with type annotations. Rather than encouraging users to file a JBS issue, directly identify the problematic annotations. Ran GHA Sanity Checks, local Tier 1 and 2, and new test directly. Patch is clean.

Marked as fix request yes, so re-opening. Will re-merge master into the branch and run test again locally to confirm it fixes the issue.
