Create HTTP.PATCH request to firebase from JAVA Spring

问题

Problem is that the Java HTTPUrlConnection does not support HTTP.PATCH.

So I found a guide that did an implementation of delete with with a body. But I'm receiving HTTP/1.1 400 Bad Request

I arrived at this:
* Import compile("org.apache.httpcomponents:httpclient:4.3.1")

Method:

@SneakyThrows
    public void firebasePatch(final PARAM p) {
        new TaskRunner() {

            @Override
            public void command() throws Throwable {
                final HttpClient httpClient = new DefaultHttpClient();
                HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000);
                PARAM p2 = p;
                String callUrl = url+".json"+"?auth="+firebaseAuth;
                HttpPatch httpPatch = new HttpPatch(callUrl);
                httpPatch.addHeader("Accept", "*/*");
                httpPatch.addHeader("Content-Type", "application/json");
//              httpPatch.addHeader("auth", firebaseAuth);

                String patchString = "{'userwallposts': {'ame_lector_dk': [{'wallPostUrl': '/wallposts/1','createdByLink': '',"+
                            "'summary': 'blah gik sig ikke en tur, og købte blah med hjem','createdDate': '20140126220550','comments': '2',"+
                            "'title': '1Blah blah blah','createdBy': 'PATCHED!','picture': 'http://images6.alphacoders.com/316/316963.jpg'}]}}";
                StringEntity entity = new StringEntity(patchString, "UTF-8");
                entity.setContentType("application/json");
                httpPatch.setEntity(entity);
                HttpResponse response = httpClient.execute(httpPatch);
                int statusCode = response.getStatusLine().getStatusCode();
                if (statusCode == 200 ? true : false) {
                    // ok
                    System.out.println("patch complete");
                } else {
                    System.out.println(response.getStatusLine());
                }

            }
        }.run(nonBlock, exceptionHandling);

    }

I'v checked that the Url+method works in Advanced Rest client, can't figure out why my Spring boot project doesn't get the same output, any help will be greatly appreciated.

There is nothing wrong with the patch statement. It's simply that my JSON was incorrect. All thanks to @DaveSyer for making my narrow sight (focusing on the method, Patch red.) expand.
