JAXRS only consider the first "Accept" header in the request

For example, If we have method like

        @GET
	@Path("/configuration")
	@Produces(MediaType.APPLICATION_OCTET_STREAM)

and request message header like

Accept-Encoding: gzip,deflate
Accept: application/vnd.vwg.mbb.vtsError_v1_0_0+xml
Accept: application/octet-stream

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.
