title: PATCH request using Jersey Client
body: <p>I want to execute a PATCH request supported by our server for testing using Jersey client. My code is as below, but I get <code>com.sun.jersey.api.client.ClientHandlerException: java.net.ProtocolException: HTTP method PATCH doesn't support output</code> exception. Can someone let me know whats wrong with the code below?</p>
  
  <pre><code>String complete_url = "http://localhost:8080/api/request";
  String request = "[{\"op\":\"add\", \"path\":\"/name\", \"value\":\"Hello\"}]";
  DefaultClientConfig config = new DefaultClientConfig();
      config.getProperties().put(URLConnectionClientHandler.PROPERTY_HTTP_URL_CONNECTION_SET_METHOD_WORKAROUND, true);
  Client client = Client.create(config);
  WebResource resource = client.resource(complete_url);
  ClientResponse response = resource.header("Authorization", "Basic xyzabCDef")
   .type(new MediaType("application", "json-patch+json"))
   .method("PATCH", ClientResponse.class, request);
  </code></pre>
  
  <p>Here is the full exception,</p>
