The value of the name_and_type_index item must be a valid index into the constant_pool table. The constant_pool entry at
that index must be a CONSTANT_NameAndType_info structure (§4.4.6) representing a field name and field descriptor (§4.3.2).
i.e. name and descriptor indexed by CONSTANT_NameAndType_info must conform to a field name and field descriptor respectively, but there is no such actual field.
