messageId Can't get normal feedback

Var：V5_1.2.5

When I use this version, the ID set by the message can't give correct feedback in the arrival callback, and always returns a self incrementing ID.

Send code
MqttMessage message = new MqttMessage();
message.setId(code);
message.setPayload(payload);
mqttAsyncClient.publish(TOPIC_PUBLISHER, message);
Callback code for delivery
MqttCallback > deliveryComplete
iMqttToken.getMessageId();

Start by tracing MqttMessage.setId(code) through mqttAsyncClient.publish and the deliveryComplete callback, focusing on iMqttToken.getMessageId(). Reproduce the reported behavior with version V5_1.2.5 and verify that the callback returns the message ID set by the caller rather than an unexpected incrementing ID.
