Jackson JAX-RS YAML Provider for Resteasy Reactive

[HknLof]

Description

After playing around with a potential solution, I ended up filing this feature request. I have class called Role, that works in the following Scenarios:

1. Accept, deserialize, serialize, and return Uni<Role> with @Consumes({MediaType.APPLICATION_JSON}) and @Produces({MediaType.APPLICATION_JSON}).
2. Media types application/x+yaml works when consuming and returning String and Uni<String> respectively, then I handle serde on my own.

The method signature looks like this:

@Post
@Consumes(...)
@Produces(...)
public Uni<Role> handle(Role role) { 
// do all the things
return Uni.createFrom().item(role);
}

Works like a charm for application/json. Throws an error for application/x+yaml.

I've added the following dependency and configured quarkus accordingly:

<dependency>
  <groupId>com.fasterxml.jackson.jaxrs</groupId>
  <artifactId>jackson-jaxrs-yaml-provider</artifactId>
</dependency>

quarkus:
  index-dependency:
    yaml:
      group-id: 'com.fasterxml.jackson.jaxrs'
      artifact-id: jackson-jaxrs-yaml-provider

Don't know if this is the appropriate channel. I also don't see any mention in the Resteasy Reactive Documentation https://quarkus.io/guides/resteasy-reactive. I attach a sample stacktrace when having the following method signature:

@Post
@Consumes({"application/x+yaml"})
@Produces({"application/x+yaml"})
public Uni<Role> handle(Role role) { 
// do all the things
return Uni.createFrom().item(role);
}

Can you attach a sample application that exhibits the problematic behavior please?
