The protocol version is not checked in any subsequent rpc which could be a problem if the server restarts with a new protocol version. This issue and also the additional round-trip at proxy creation can be avoided if we add the protocol version in every rpc, and server checks the protocol version for every call. -- This message is automatically generated by JIRA.
