I don't think they need special treatment currently. The Method/Constructor/Field instances created by native code and returned via native methods are always the `root` objects that are never handed to user code. They are used internally in the caches and are published to other threads via volatile field write/read (see `java.lang.Class.ReflectionData`). User code only sees copies of those objects which are performed using constructors.
