Description

The correct response is to send back a supported header[1] before closing the socket. This worked for 0.8 but is broker from 0.9 onwards, I believe by this commit: https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;a=commit;h=1b2be03c748ef5a57cf181f8373b9b6e8f8cfd22

It means anything relying on proton-c for protocol header handling is not compliant with the spec.

[1] section 2.2 of spec: "If the requested protocol version is not supported, the server MUST send a protocol header with a supported protocol version and then close the socket."
