I think I know the reason.
Are you seeing this issue during the tests ?
When doing something like this:
WebClient wc = WebClient.create("http://bar";);
wc.accept("application/json");
wc.get();
wc.accept("application/xml");
wc.get();
?
When a single instance is used, it accumulates header values, for those
headers which can have multiple values. The earlier version probably did
not do it.
So the above is equivalent to
wc.accept("application/json").accept("application/xml");
wc.get();
wc.get();
or
wc.accept("application/json", "application/xml");
wc.get();
wc.get();
Thus if you prefer to use a single WebClient instance, then do
webClient.reset() between the .accept() calls.
I'll also add resetHeader() or replaceHeader to make things simpler for
cases like this, as reset would also reset queries.

Actually, reproduced, hmm, looks like a regression possibly caused by

Works for me OK.
I have @Produces({"application/json", "application/xml"})
and then use WebClient to accept json or xml, works as expected.
How does a request URI look like ? Does Accept has only a single value,
can you capture the http trace ?
Thanks, Sergey

Subject: Why isn't a service similar to another one not respecting the
"Accept" header?
I've had a CXF-based REST service in production for a little while. It
changes its response format either with the "Accept" header, or by
extension. I get xml with "Accept:application/xml" or if I add the
".xml" suffix to the request. Similarly, I get JSON with the analogous
values for JSON. This service is using Jackson for its JSON
representation.
I now have another service that will go to production soon. Using the
suffix for xml or json works fine. However, it seems to ignore the
"Accept" header. My "@Produces" annotation has both "application/json"
and "application/xml", in that order. I get JSON by default, and I
still get JSON if I send "Accept:application/xml" as an HTTP header.
Just to make sure, I retested this same mechanism with the other
service, and it correctly changes the format based on the "Accept"
header.
One difference between the two services is that the new service isn't
using Jackson, it's using the default (Jettison, I assume). Otherwise,
the "jaxrs:server" and other configuration is almost identical between
the two services.
Another difference is that the new service is using CXF 2.4.2, and the
older service is using CXF 2.3.3.
Before I start pasting in my configuration and code, are there any
simple reasons why this might not be working?
