Missing MessageMethodArgumentResolver default constructor [SPR-14616]

[spring-projects-issues]

Juergen Hoeller opened SPR-14616 and commented

As raised in spring-projects/spring-kafka#172, MessageMethodArgumentResolver has a breaking change in 4.3 in that its default constructor got substituted with one accepting a MessageConverter. Let's reintroduce a default constructor side by side for backwards compatibility.

MessageMethodArgumentResolver may work without a MessageConverter now in case of no payload conversion needed. The default constructor simply sets no such converter to begin with.

Juergen, thank you for fixing this!

Yes, I saw such a problem when we implemented null payload feature in Spring Kafka, but didn't pay attention that it really may be such a breaking change in SF.

Right now I would like to have an appropriate 4.3.3.BUILD-SNAPSHOT to test that issue and close as Works as Designed.

Thank you one more time!
