javax.management.remote.message.VersionMessage

This class represents the handshake messages exchanged between the client and the server to agree on the protocol version.

The protocol version is implicitly negotiated by the client and the server when necessary at the beginning of the handshake phase.

Refer to the {@link HandshakeBeginMessage HandshakeBeginMessage}documentation for a full description of how the protocol version is negotiated.

The textual representation of the protocol version must be a series of non-negative decimal integers each separated by a period from the one that precedes it. For example, "1.0" is earlier than "1.0.1" and "2.0". @see HandshakeBeginMessage

                if (clientVersion.compareTo(serverVersion) > 0) {
                    throw new IOException("The client is already using the " +
                                          "lowest JMXMP protocol version [" +
                                          clientVersion + "]");
                } else {
                    VersionMessage cjmxmp = new VersionMessage(clientVersion);
                    mc.writeMessage(cjmxmp);
                    msg = mc.readMessage();
                    if (msg instanceof VersionMessage) {
                        VersionMessage sjmxmp = (VersionMessage) msg;
                        if (!clientVersion.equals(sjmxmp.getVersion())) {
                            throw new IOException("Protocol version " +
                                                  "mismatch: Client [" +
                                                  clientVersion +
                                                  "] vs. Server [" +
                                                  sjmxmp.getVersion() + "]");
                        }
                    } else if (msg instanceof HandshakeErrorMessage) {
                        // Throw exception and let GenericConnector
                        // close the connection
