The features stanza sent to the client says that client can either start TLS or login using X-GOOGLE-TOKEN. Because X-GOOGLE-TOKEN is not documented and subject to change, your only choice is to start TLS by sending <starttls/> to the server.
After the stream is started on TLS, the server will send the client a features stanza containing SASL PLAIN. I recommend using SASL authentication (XMPP Core, section 6) instead of Non-SASL Authentication (JEP-078). I'll update the error messages to make them more clear.
