Currently there is no way, but we could do something like specializing @bodyParam with an empty field name: 

@bodyParam("app", "")
App postApps(App app);

It would then error out of there are other body parameters and otherwise would write the contents directly into the response body.

Great, but I'm not sure that the @bodyParam("app", "") is a good idea because 

{
  "": "value"
}

is valid JSON object. Maybe @bodyParam("app") will be better in this case. What do you think?
