Claude Warren commented on SSHD-720:
------------------------------------

Just as a quick note:

org.apache.sshd.server.scp.UnknownCommand.java contains

{code}
public void start(Environment env) throws IOException {
        Objects.requireNonNull(err, "No error stream");
        String errorMessage = getMessage();
        try {
            err.write(errorMessage.getBytes(StandardCharsets.UTF_8));
            err.write('\n');
        } finally {
            err.flush();
        }
        if (callback != null) {
            callback.onExit(1, errorMessage);
        }
    }

{code}

That is where I drew my example Command code from.
