Buggy source:

  URL url=null;

  }

  }

  final int port=url.getPort() == -1 ? url.getDefaultPort() : url.getPort();
  final ChannelFuture retVal;
  final ChannelFuture connectFuture=bootstrap.connect(new InetSocketAddress(host,port));
  if ("String_Node_Str".equals(url.getProtocol())) {
    if (sslContext == null) {
      throw new IllegalStateException("String_Node_Str");
    }
    final SSLEngine sslEngine=sslContext.createSSLEngine(host,port);
