> Stream creates by File.walk should be closed, like jdk said:
> * <p> The returned stream encapsulates one or more \{@link DirectoryStream}s.
> * If timely disposal of file system resources is required, the
> * {@code try}-with-resources construct should be used to ensure that the
> * stream's \{@link Stream#close close} method is invoked after the stream
> * operations are completed. Operating on a closed stream will result in an
> * {@link java.lang.IllegalStateException}.
