JERSEY Upload file in Google App Engine

[David via StackOverflow]

Trying to handle file uploading in Google App Engine using JERSEY2.9.

JERSEY Service:

      @POST
      @Consumes(MediaType.MULTIPART_FORM_DATA)
      @Produces("text/plain")
      @Path("/upload") 
      public String uploadPics( 
                                @FormDataParam("petpics") InputStream fileInputStream,
                                @FormDataParam("petpics") FormDataContentDisposition contentDispositionHeader,
                                @Context HttpServletRequest sevletRequest,
                                @Context HttpServletResponse servletResponse) throws IOException {
                  return "";
}

Error message:
