  Fix Debug build on Monterey (Missing SoftLinked classes)

Reviewed by Alex Christensen.

Monterey has at least one softlinked framework in place, but with a class that is missing.
The build was fine, but oh boy was using it in a Debug configuration very unhappy.

This situation used to be fine when we looked up allowed classes in a Vector (search for null is fine)
After we moved to looking up allowed classes in a HashSet...  Search for null is no longer fine.

This change simply null checks any softlinked class being looked up in the set.
