Sergey Beryozkin commented on CXF-7607:
---------------------------------------

Makes sense to collapse it into a single list at the http transport level

> For example, If we have method like
> {code}
>         @GET
> 	@Path("/configuration")
> 	@Produces(MediaType.APPLICATION_OCTET_STREAM)
> {code}
> and request message header like
> {code}
> Accept-Encoding: gzip,deflate
> Accept: application/vnd.vwg.mbb.vtsError_v1_0_0+xml
> Accept: application/octet-stream
> {code}
> We will run into "HTTP 406 Not Acceptable "
> However the request should be valid as the second "Accept" is
> Accept: application/octet-stream
> which match the 
> @Produces(MediaType.APPLICATION_OCTET_STREAM)
> so the request is acceptable. 
> I checked the the W3C spec here[1], multiple "Accept" headers is allowed  and should be given same significance as if all the entries has been in one field.
