Content Negotiation Problem with Jackson XML

[JEDIBC]

Hi,

The content negociation depending on the accept http header doesn't work (or there's some configuration not described in the doc)

Steps to Reproduce

1. Create a 1.3 project
2. Add https://github.com/micronaut-projects/micronaut-jackson-xml dependency to be able to bind & serialise XML
3. Create a controller with @Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}) and @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
4. call your controller with the accept: application/xml header

Expected Behaviour

The result should be in XML.

Actual Behaviour

The result is still in JSON

I must say that if you only need XML output and add @Produces(MediaType.APPLICATION_XML) in your controller, the ouput is correctly serialized in XML.

Environment Information

• Operating System: Ubuntu 18.04
• Micronaut Version: 1.3.0
• JDK Version: 11.0.5

Thanks

In addition, if I call the controller with a not managed content type, say accept: text/csv it still return JSON instead of returning a 406 Not Acceptable return code.
