title: Java Eclipse Paho Implementation - Auto reconnect
body: <p>I'm trying to implement <code>eclipse.paho</code> in my project to connect Mqtt Broker (Both subscribing and publishing purpose). The problem is, when I using the subscribing feature (Implementing <code>MqttCallback</code> interface), I couldn't figure our how can I reconnect if the connection lost. MqttCallback interface has a connectionLost method, but it is useful for the debug what causes the connection lost. I searched but couldn't find a way to establish auto reconnect. Can you suggest a way or document about this problem? </p>
