> In a WriterInterceptor, one expects to be able to modify response headers via:
> //here using putSingle() but could also use on of the addXXX variants
> context.getHeaders().putSingle("headerName", headerValue);
> However, above is not working in 2.7.5/2.7.6 (@see JIRA-4986)
> As a workaround, one should be able to inject the HttpServletResponse object via: @Context HttpServletResponse response;
> then be able to add headers directly to the response object e.g.,
> response.setHeader("headerName", headerValue);
> however, above is also not working in (2.7.5/2.7.6). This is not always reproducable as sometimes my client does see the new headers in the received response. On closer look it seems the added headers get lost when it is a @GET request as opposed to e.g., a @POST. Basically, my test case (a @GET) always fails with a missing header in the received response even though I am pretty sure the server had added the header.
