Certainly the decisive answer would be: in the same way as HTTP spec
does. But unfortunately, I can't find relevant spec part that explicitly
says that content type of 'type/subtype;key=value' matches Accept header
of 'type/subtype'. The examples in [1] suggests so, as does the practice
of browser 'Accept' header.

So, in my opinion, the

  @Produces("text/plain;charset=utf-8")

should be considered as matching the relevant client's

  request.accept("text/plain");
