Viktor Isaev commented on IO-486:
---------------------------------
I'm not speaking against short-circuit in {{IOUtils.toByteArray()}} - I'm
speaking for a similar short-circuit in {{FileUtils.readFileToString()}} (and
in {{FileUtils.readFileToByteArray()}} where we are guaranteed to uselessly
open and close a stream in this case).
Well, it's just a suggestion.
> FileUtils.readFileToString() can immediately return empty string if file
> length is zero

> If {{file.length() == 0}}, there is no point of doing extra work of opening
> and closing an input stream - we can return an empty string right away.
> Same applies for {{FileUtils.readFileToByteArray()}} and
> {{FileUtils.readLines()}}.
