It would preferable if this were the base class containing the pointer but that would require

Check if this object is properly registered for metadata tracking. All classes which implement this interface must be registered with the HotSpotJVMCIMetaAccessContext.add unless they are kept alive through other means. Currently the only type which doesn't require explicit registration is HotSpotResolvedObjectTypeImpl since it's kept alive by references to the Class.
