static void ensureVersionCompatibility(Version version, Version currentVersion, boolean isHandshake) {
    // for handshakes we are compatible with N-2 since otherwise we can't figure out our initial version
    // since we are compatible with N-1 and N+1 so we always send our minCompatVersion as the initial version in the
    // handshake. This looks odd but it's required to establish the connection correctly we check for real compatibility
    // once the connection is established
