Answer 1

The solution is add MqttClient.generateClientId

MemoryPersistence persistence = new MemoryPersistence()
MqttClient client = new MqttClient("tcp://192.168.88.203",MqttClient.generateClientId(),persistence); 
client.connect();

or

MqttClient client = new MqttClient("tcp://192.168.88.203", MqttClient.generateClientId+SERVER_CLIENTID_PREFIX)

The identifier must be random. I had this problem in scala and that was my solution.
