Issue downloading pact files from broker

[SnewsButton]

Peeking into the code a bit, I see that CloseableHttpResponse response = createClient().execute(request); yields the following 406 error:

HttpResponseProxy{HTTP/1.1 406 Not Acceptable [Content-Length: 0, Connection: keep-alive, Status: 406 Not Acceptable, Date: Tue, 10 Jul 2018 20:05:59 GMT, X-Content-Type-Options: nosniff, Server: Webmachine-Ruby/1.5.0 Rack/1.3, X-Pact-Broker-Version: 2.24.0, X-Powered-By: Phusion Passenger 5.1.11] [Content-Length: 0,Chunked: false]}

However it seems that this code snippet works as intended:

CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(path);
CloseableHttpResponse response = httpclient.execute(httpGet);

I am not sure what the difference between the two function calls is. Any help would be appreciated.
