Buggy source:
public static void main(String[] args) throws InterruptedException {
  Bootstrap bootstrap=new Bootstrap();
  bootstrap.group(new NioEventLoopGroup()).channel(NioSocketChannel.class).handler(new ChannelInitializer(){
    @Override protected void initChannel(    Channel ch) throws Exception {
      ch.pipeline().addLast(SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build().newHandler(ch.alloc(),"String_Node_Str",443));
      ch.pipeline().addLast(new HttpClientCodec());
      ch.pipeline().addLast(new HttpObjectAggregator(81920000));
      ch.pipeline().addLast(new ChannelInboundHandlerAdapter(){
        @Override public void channelRead(        ChannelHandlerContext ctx,        Object msg) throws Exception {
          System.out.println(msg.toString());
        }
      }
);
    }
  }
);
  ChannelFuture cf=bootstrap.connect("String_Node_Str",443).sync();
  HttpRequest httpRequest=new DefaultFullHttpRequest(HttpVersion.HTTP_1_1,HttpMethod.GET,"String_Node_Str");
  httpRequest.headers().add(HttpHeaderNames.HOST,"String_Node_Str");
  httpRequest.headers().add(HttpHeaderNames.USER_AGENT,"String_Node_Str");
  httpRequest.headers().add(HttpHeaderNames.CONTENT_LENGTH,0);
  System.out.println(httpRequest.toString());
  cf.channel().writeAndFlush(httpRequest);
}

Fixed version (ground truth):

    @Override protected void initChannel(    Channel ch) throws Exception {
      ch.pipeline().addLast(new HttpClientCodec());
      ch.pipeline().addLast(new HttpObjectAggregator(81920000));
      ch.pipeline().addLast(new ChannelInboundHandlerAdapter(){
        @Override public void channelUnregistered(        ChannelHandlerContext ctx) throws Exception {
          System.out.println("String_Node_Str");
          super.channelUnregistered(ctx);
        }
        @Override public void exceptionCaught(        ChannelHandlerContext ctx,        Throwable cause) throws Exception {
          System.out.println("String_Node_Str");
          super.exceptionCaught(ctx,cause);
        }
        @Override public void channelRead(        ChannelHandlerContext ctx,        Object msg) throws Exception {
          System.out.println(msg.toString());
        }
      }
