MQTT MessageArrived IO exception

Hi

Using this sub:

Code:

  Private Sub mqtt_MessageArrived (Topic As String, Payload() As Byte)
Dim obj As Object = serializator.ConvertBytesToObject(Payload)
Dim s As String = obj

  Label2.Text = s
End Sub  

Just at start up, and after that, if I choose 'continue', on each message arriving, I get:

java.io.IOException:
