Buggy source:
@Override public HttpResponse execute(HttpRequest request) throws HttpClientException {
  HttpResponse response=null;
  try {
    HttpRequestBase uriRequest=methodMap.get(request.getMethod());
    uriRequest.setURI(request.getURI());
    boolean useSSL="String_Node_Str".equals(request.getURI().getScheme());
    SSLContext sslContext=null;
    X509HostnameVerifier hostnameVerifier=null;
    HttpParams params=request.getParams();
    if (params != null) {
      Builder requestConfig=RequestConfig.custom().setSocketTimeout(params.getSocketTimeout()).setConnectTimeout(params.getConnectTimeout()).setConnectionRequestTimeout(params.getReadTimeout());
      if (params.getProxy() != null) {
        InetSocketAddress socketAddress=(InetSocketAddress)params.getProxy().address();
        HttpHost proxy=new HttpHost(socketAddress.getHostName(),socketAddress.getPort());
        requestConfig.setProxy(proxy);
        useSSL=false;
      }
      uriRequest.setConfig(requestConfig.build());
      sslContext=params.getSSLContext();

      }
      if (hostnameVerifier == null) {
        hostnameVerifier=SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;
      }
      httpClient=HttpClients.custom().setHostnameVerifier(hostnameVerifier).setSslcontext(sslContext).build();
    }
    addHeaders(request.getHeaders(),uriRequest);

Fixed version (ground truth):

    SSLContext sslContext=null;
    X509HostnameVerifier hostnameVerifier=null;
    HttpParams params=request.getParams();
    if (params != null) {
      Builder requestConfig=RequestConfig.custom().setSocketTimeout(params.getSocketTimeout()).setConnectTimeout(params.getConnectTimeout()).setConnectionRequestTimeout(params.getReadTimeout());
      if (params.getProxy() != null) {
        InetSocketAddress socketAddress=(InetSocketAddress)params.getProxy().address();
        HttpHost proxy=new HttpHost(socketAddress.getHostName(),socketAddress.getPort());
        requestConfig.setProxy(proxy);
        useSSL=false;
      }
      uriRequest.setConfig(requestConfig.build());
      sslContext=params.getSSLContext();
      hostnameVerifier=new CustomHostnameVerifier(params.getHostnameVerifier());

      }
