Description

I use several services, some of them connect over tcp and the LWT works properly.
I use several clients from a webapp' connected over a websocket link.

i use a javascript code:

var i_am_disconnected = new Paho.MQTT.Message(JSON.stringify({
        version: 1,
        state: 0
      }));
      i_am_disconnected.destinationName = "device/" + _token + "/ping";
      i_am_disconnected.retained = true;
      i_am_disconnected.qos = 1;
client.onConnectionLost = onConnectionLost;
      client.connect(…

i traced the ActiveMQ log, i can see that the disconnection is detected, but i didn't receive my LWT message. (again, my LWT works when I use a tcp connexion)
