[thboileau]

tested scenario:

• application using the internal connector
• using the Jackson extension
• client asks for yaml representation of a Java bean

This issue is not considered as high for two reasons:

• the response is correctly sent
• the internal connector is not suggested for production environment. Preferred connectors: the ones based on Jetty, Simple, or servlet container
