Description

Exception:

java.lang.ClassCastException: java.net.URI cannot be cast to java.lang.String

Test:

 Response response = getWebClient()
                .path("/blob")
                .type(MediaType.MULTIPART_FORM_DATA)
                .post(multipartBody);

serverside resource:

        URI blobId = UriBuilder.fromResource(getClass()).build(gridFSDBFile.getId());
        return Response.created(blobId).build();

because inside WebClient handleResponse -> AbstractClient the values are assumed to be string arrays, but is an URI object:

 boolean splitHeaders = 
            MessageUtils.isTrue(outMessage.getContextualProperty(HEADER_SPLIT_PROPERTY));
        for (Map.Entry<String, List<String>> entry : protocolHeaders.entrySet()) {
            if (null == entry.getKey()) {
                continue;
            }
            if (entry.getValue().size() > 0) {
                if (HttpUtils.isDateRelatedHeader(entry.getKey())) {
                    currentResponseBuilder.header(entry.getKey(), entry.getValue().get(0));
                    continue;                    
                }
                for (String val : entry.getValue()) {
                    if (splitHeaders) {
                        String[] values;
                        if (val == null || val.length() == 0) {
