      sun.reflect.ReflectionFactory::newConstructorForSerialization is JDK unsupported API used by 3rd party serialization framework.

      This API currently generates the bytecode which fails the verification because `new C; invokespecial A()` where the given class `C` and invoke a no-arg constructor of `C`'s first non-`Serializable` superclass `A` is not a valid operation per the VM specification. VM special cases the classes generated for reflection to skip verification for the constructors generated for serialization and externalization. See [1] for details.

      Reimplementing ReflectionFactory::newConstructorForSerialization with method handles will allow the VM hack to be removed.
