@Override
public void setState(InputStream input) {

    // NOTE: since we know that incrementing the count and transferring the state
    // is done inside the JChannel's thread, we don't have to worry about synchronizing
    // messageCount. For production code it should be synchronized!
    try {
        // Deserialize
        messageCount = Util.objectFromStream(new DataInputStream(input));
    } catch (Exception e) {
        System.out.println("Error deserialing state!");
    }
    System.out.println(messageCount + " is the current messagecount.");
