Avoid final field mutation in UnsafeUtils #10476

sarahchen6 · 2026-01-29T21:44:08Z

What Does This Do

When attempting to clone a final field using UnsafeUtils::cloneFields, skip and instead emit a debug warning that final fields cannot be mutated. Update tests to reflect this as well.

Motivation

Prepare for JEP 500 which disallows final field mutations.
