Body argument missing for consumes=MediaType.ALL endpoints

[fabienrenaud]

Steps to Reproduce

1. Write a simple controller:

public class App {

  @Controller
  public static class Control {

    @Post(value = "/example/bug", consumes = MediaType.ALL)
    public Object ep(@Body Object body) {
      return body;
    }
  }

  public static void main(String[] args) {
    Micronaut.run(App.class, args);
  }
}

2. Run and curl:

curl localhost:8080/example/bug --data 'foobar'

Returns:

{"message":"Required Body [Object body] not specified","path":"/body","_links":{"self":{"href":"/example/bug","templated":false}}}

Expected Behaviour

The request should routed to the defined endpoint when the body can be mapped to the desired type. Here it is Object, but String and byte[] should also work.
I should not have to pass -H "Content-Type: */*" in my curl to get the response.

Actual Behaviour

Call is not routed to the desired endpoint.
I have to set the content-type of the request to */* to get it routed to the handler and get the desired response:

curl localhost:8080/example/bug --data 'foobar' -H "Content-Type: */*"
