Payload value must not be empty for Acknowledgment parameter

**Affects Version(s):2.6.5

Copying from https://github.com/spring-projects/spring-framework/issues/26389 since it seems this is right place for it.

I have a @KafkaListener with this signature:

    @KafkaListener(topics = "${matcher.reply.channel:matcher_response${matcher.kafka.topic.suffix}}")
    public void processMessage(@Payload ConsumerRecord<String, String> record, Acknowledgment acknowledgment) {

When I receive a message I get an exception that Payload value must not be empty about the acknowledgment parameter:

It seems that the PayloadMethodArgumentResolver (or the KafkaNullAwarePayloadArgumentResolver that inherits from it) handles an argument that it shouldn’t. I thought it might be a compatibility issue and aligned my dependencies with the matrix here: https://spring.io/projects/spring-kafka But that did not prevent the exception.

Removing the Acknowledgement argument worked around the problem for me but for some scenarios it may be required and can’t be removed
