How to ignore SSL certificate errors in Apache HttpClient 4.4

public static CloseableHttpClient acceptsUntrustedCertsHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        HttpClientBuilder b = HttpClientBuilder.create();

        // setup a Trust Strategy that allows all certificates.
        //
        SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
            public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
                return true;
            }
        }).build();
        b.setSslcontext( sslContext);

        // don't check Hostnames, either.
        //      -- use SSLConnectionSocketFactory.getDefaultHostnameVerifier(), if you don't want to weaken
        HostnameVerifier hostnameVerifier = NoopHostnameVerifier.INSTANCE;

        // here's the special part:
        //      -- need to create an SSL Socket Factory, to use our weakened "trust strategy";
        //      -- and create a Registry, to register it.
        //
        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
        Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", PlainConnectionSocketFactory.getSocketFactory())
                .register("https", sslSocketFactory)
                .build();

        // now, we create connection-manager using our Registry.
        //      -- allows multi-threaded use
        PoolingHttpClientConnectionManager connMgr = new PoolingHttpClientConnectionManager( socketFactoryRegistry);
        b.setConnectionManager( connMgr);

        // finally, build the HttpClient;
        //      -- done!
        CloseableHttpClient client = b.build();
        return client;
    }
