>> Backporting JDK-8334756: javac crashed on call to non-existent generic method with explicit annotated type arg. 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.

Confirmed test passing locally, I'll let the GHA tests complete before merging
