Analysis org.eclipse.paho.client.mqttv3.internal.ConnectActionListener

public void connect() throws MqttPersistenceException { MqttToken token = new MqttToken(client.getClientId()); token.setActionCallback(this); token.setUserContext(this);

**persistence.open(client.getClientId(), client.getServerURI());**

if (options.isCleanSession()) {
  persistence.clear();
}

if (options.getMqttVersion() == MqttConnectOptions.MQTT_VERSION_DEFAULT) {
  options.setMqttVersion(MqttConnectOptions.MQTT_VERSION_3_1_1);

I get this error too, when using a callback: subscribe.callback(on_message_printLCD, "#", hostname="10.0.1.x", auth = {"username":"xxxxxxxx", "password":"xxxxx"}) ...all works fine for a few days then I get :
