For legacy protocol version incompatibility with non linux RDS, consumer reject reason being used to convey it to peer. But the choice of reject reason value as '1' was really poor. Anyway for interoperability reasons with shipping products, it needs to be supported. For any future versions, properly encoded reject reason should to be used.
