Access to sessionPresent after automatic reconnect

[fabianzwodrei]

Thanks for this fork and the maintenance.

I am testing a persistent connection between app and broker: I am using the sessionPresent flag after a successul connection to decide if a new subscription is necessary: If server acknowlegdes the connection and set the sessionPresent=true, the app wont need new subscriptions.

But I can't access the sessionPresent flag after a automatic reconnect, because the onSuccess-callback of my IMqttActionListeneris not called. Only the IMqttActionListener onSuccess-callback contains the token for that flag

Am I wrong with my concept of connection and subscription - or might it be useful to implement some sort of access to that sessionPresent flag during the reconnection?

Hmm, is there a call onSuccess() missing ? Anyway, if you found a solution, I'm happy to approve the solution !

The onSuccess Method of org.eclipse.paho.client.mqttv3 is called in case of a successful reconnect but there is only a MqttReconnectActionListener as a callback called but not the onSuccess of my IMqttActionListener

I debugged this loc: https://github.com/eclipse/paho.mqtt.java/blob/6f35dcb785597a6fd49091efe2dba47513939420/org.eclipse.paho.client.mqttv3/src/main/java/org/eclipse/paho/client/mqttv3/internal/ConnectActionListener.java#L87

My workaround at the moment is to disable automatic Reconnect. And to reestablish the connection after 3secs

Note: The first connection made through MqttAndroidClient.connect(...) where I can set the callback to my callback, works perfectly. OnSuccess is called and I can access the sessionPresent comming from the broker server
