JSONP doesn't use Accept-Header application/json

Description
If using $.getJSON() or $.ajax() with datatype jsonp or with datatype json and callback=? in the url, the Accept Header of the request is set to */* instead of application/json.
In my case this forces the REST server to respond with application/xml.
The same problem was issued in Ticket #6551, but it was set to invalid. I think this is a valid bug. So I create a new ticket for this.

Additionally, the correct way to address a bug that has been closed is to post a re-open request ON THAT TICKET with a valid, reduced test case. #6551

Thanks for taking the time to contribute to the jQuery project by writing a bug report. After checking your report and making up a live test case I came to the conclusion that this is not a bug.
If you check the documentation on jQuery.ajax() you will find several statements related to
jsonpbut I guess this one should explain what happens.>When data is retrieved from remote servers (which is only possible using the
scriptorjsonpdata types), the operation is performed using a<script>tag rather than anXMLHttpRequestobject.Because of the same origin policy it isn't possible to use
XMLHttpRequestto make a cross-domain jsonp request instead the solution described above is used. This naturally means that jQuery can't possibly influence the accept header as loading the<script>is handled by the browser. In FF and Chrome thus you will see*/*as accept header value. So this is a bug on the REST server which should know that request to a certain URL in a certain format should mean "RETURN JSONP".
