> With MQTT 3.1.1, when PUBLISH QoS2 packet failed (custom LoginModule throw ActiveMQSecurityException based on time), the client reconnect with valid credential and resend the same PUBLISH packet. The server ignores and logs:
> {noformat}
> AMQ834009: Ignoring duplicate MQTT QoS2 PUBLISH packet for packet ID client from client with ID XX.{noformat}
> Server session state is not handling the failed PUBLISH packet so PUBLISH packet with the same packet ID no longer be handled.
