Description

if you marshal to json then send to a HTTP endpoint you'll be missing the fact that the payload is now in JSON format. It seems a reasonable default to add this - so that a HTTP endpoint can know it can parse the payload as JSON.

e.g.

from("activemq:foo.bar").
  to("dataformat:json-jackson:marshal").
    /// TODO camel should now expose that the content type is json
  to("http://foo.bar/")
