>
> FileUtils.iterateFiles goes out of memory when executed for a directory with
> large number of files because it uses the listFiles method which returns an
> array of java.io.File objects. The iterator itself should not be derived from
> a list but from a Java Stream which will have lesser memory footprint. This
> feature however can be used only with Java 8 or later because streams were
> introduced only in Java 8.
