When I run a MQTT client(paho or fuse)to connect ActiveMQ broker. if i terminate this
client and can not receive LWT messages from broker.

I changed broker from ActiveMQ to Mosquitto broker , everything is ok.

below is my test class:

package com.paho;

import org.eclipse.paho.client.mqttv3.MqttCallback;
import org.eclipse.paho.client.mqttv3.MqttClient;
import org.eclipse.paho.client.mqttv3.MqttConnectOptions;
import org.eclipse.paho.client.mqttv3.MqttDeliveryToken;
import org.eclipse.paho.client.mqttv3.MqttException;
import org.eclipse.paho.client.mqttv3.MqttMessage;
import org.eclipse.paho.client.mqttv3.MqttSecurityException;
import org.eclipse.paho.client.mqttv3.MqttTopic;

public class Sub {
	private MqttClient mqttClient;
	
	public void subscriber(){
		try {
			mqttClient = new MqttClient("tcp://192.168.100.80:1883", MqttClient.generateClientId());
			

			MqttConnectOptions connectOptions = new  MqttConnectOptions();

			//set will
			connectOptions.setWill(mqttClient.getTopic("lastwill"), new String("I am offline").getBytes(),
1, false);
			mqttClient.connect(connectOptions);
			mqttClient.setCallback(new MqttCallback(){

				public void connectionLost(Throwable paramThrowable) {
					System.out.println("Connection Exist. \nCause: " + paramThrowable);
					while(true){
						try {
							Thread.sleep(20000);
							if(!mqttClient.isConnected()){
								subscriber();
							}
						} catch (InterruptedException e) {
							e.printStackTrace();
						}
					}
				}

				public void messageArrived(MqttTopic paramMqttTopic,
						MqttMessage paramMqttMessage) throws Exception {

					System.out.println("Message arrived From The Topic:\t"+paramMqttTopic.toString() +" \nMessage:
" + paramMqttMessage.toString());
				}

				public void deliveryComplete(
						MqttDeliveryToken paramMqttDeliveryToken) {
				}
				
			});
			
			mqttClient.subscribe("durable",1);
//			mqttClient.subscribe("durable1",1);

			
		} catch (MqttException e) {
			e.printStackTrace();
		}

	}
	

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Sub sub = new Sub();
		sub.subscriber();
	}

}
