> Currently if an exception occurs while UserServer is handling handshake message from
UserClient, server terminates the connection which causes the client to not handle the handshake
response properly. 
> This JIRA is to modify the behavior of UserServer when an exception occurs or contents
(ex. user/password credentials) of handshake request are not valid to:
> -- First send a handshake response message with error details 
> -- Then terminate the connection.
> As the client always receives the handshake response, it can inform the application about
the error if the response has any.
