micronaut-core: Lombok + @Introspected generates incorrect parameter names

Summary

The TLDR is that this simple class

@Introspected
@Value
public class Payload {
  private final String id;
}

leads to different parameter names:

// id
Payload.class.getConstructors()[0].getParameters()[0].getName();

// arg0
BeanIntrospection.getIntrospection(Payload.class).getConstructorArguments()[0].getName();

The longer version is that a application.yml:

jackson:
    bean-introspection-module: true

and a controller:

  @Post
  public String create(@Body Payload body) {
    return body.getId();
  }

fails when doing:

POST /bad

{
  "id": "123"
}

with a stack trace like:

io.micronaut.http.client.exceptions.HttpClientResponseException: Failed to convert argument [body] for value [null] due to: Cannot construct instance of `micronaut.introspection.issue.Payload`, problem: Null argument specified for [arg0]. If this argument is allowed to be null annotate it with @Nullable
     at [Source: UNKNOWN; line: -1, column: -1]

It fails in both gradle and maven.

Strangely, it works in eclipse.
