When server had some error, after client reconnect success, cann't receive any message

[lycherish]

Hi Team,

Jmeter (V5.1.1) not receiving MQTT message when the below server exception occurs. Please help
xmeter JAR : mqtt-xmeter-2.0.2-jar-with-dependencies.jar
Test Scenario: Cluster high-availability scenarios, jmeter connect nginx server, and then subscriber topic,after the server occur, the client can automatically reconnect, and expect to continue receiving new messages

Exception:
After the server is disconnected, the client is automatically reconnected, there is a new connect between client and server, but somebody else publish a new msg, the Mqtt Sub Sampler can not receive new message.

I guess when reconnect succuess, the sampler don't know the connect changed,and there is no monitor for connect change.

Could you help me fix this issue, thank you very much.
