My workaround of this limitation was to set inheritHeaders in the factory method creating the proxy client and then set Accept header to application/json:

{code}
final JAXRSClientFactoryBean bean = new JAXRSClientFactoryBean();
...
bean.setInheritHeaders(true);
...
RestApiClient client = bean.create(RestApiClient.class);
...
WebClient.client(client).header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON);
...
return client;
{code}

Thanks for the proposed solutions that caused me to think of some other alternatives.

> @Produces has no effect on CXF if the annotated method returns void. The "accept" is set to default "\*/\*".
> Though it looks right for successful calls of the method, it starts causing issues when there are different type of responses in case of an error.
> For example:
> {code}
>  @PUT
>  @Path("{id}/info")
>  @Consumes(MediaType.APPLICATION_JSON)
>  @Produces(MediaType.APPLICATION_JSON)
>  void setInfo(@PathParam("id") String documentId, StorageObject newInfo);
> {code}
> No response is expected on success.
> However when the passed StorageObject contains some invalid data the server responds with "HTTP/1.1 400 Bad Request" and the body contains detailed information about which fields contain invalid values.
> That information can be send either as JSON or as XML data, but I cannot make CXF to specify which format I want the error to be sent in.
> The issue is in
> org.apache.cxf.jaxrs.client.ClientProxyImpl.setRequestHeaders(MultivaluedMap<String, String>, OperationResourceInfo, boolean, Class<?>, Class<?>)
> method, namely in lines 359-360 (cxf-rt-frontend-jaxrs-2.7.16.jar):
> {code}
>             } else if (responseClass == Void.class || responseClass == Void.TYPE) {
>                 accepts = Collections.singletonList(MediaType.WILDCARD_TYPE);
> {code}
> which I would like to remove.
> As a workaround I'm using my own Void class not to satisfy the above part of the if statement
