reactive-messaging extension fails to lookup generic payload converter #42315

Open

Description

Describe the bug

While debugging some converter selection issues, I figured out that quarkus is (intentionally?) returning the message payload's raw type (at least here and here, but there are more).

As smallrye converters allow for generic message payloads (linked from the quarkus kafka reference guide), I was expecting parameterized types to be handled correctly (at least the ones without type variables and wildcards).

Expected behavior

Payload's parameterized type is being used for message converter lookup.

Actual behavior

Payload's raw type is being used for message converter lookup.
