> UnregisteredClassesTable_lock is never created in mutex_init() and is always nullptr. This lock is referenced in a few places and all of those are effectively thread unsafe. Some of the places `unregistered_classes_table` is accessed are under other locks, so the rank of this lock has to be adjusted appropriately. The lock will be initialized to enable the intended behavior. Verified with tier 1-4 tests.
