Since a lambda proxy class is a hidden class, a nestmate of the host class, it can invoke the private implementation method but it has to use `REF_invokeVirtual` or `REF_invokeInterface`.   In order to support the old classes running on the new runtime, LMF implementation adjusts the reference kind from `REF_invokeSpecial` to `REF_invokeVirtual/REF_invokeInterface`.
