> 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.
