Hi @zhangminglei ,
Good catch! Maybe the Reader may also need to be adapted, making `new
InputStreamReader` to `Channels.newReader`. I find a benchmark about File
InputStream and Reader
[here](https://arnaudroger.github.io/blog/2017/03/20/faster-reader-inpustream-in-java.html).
Hope it helps.

> They rely on finalizers (before Java 11), which create unnecessary GC load.
> The alternatives, Files.newInputStream, are as easy to use and don't have
> this issue.
