Subject [jira] [Commented] (IO-486) FileUtils.readFileToString() can immediately return empty string if file length is zero
Date Mon, 09 Nov 2015 15:11:11 GMT

Sebb commented on IO-486:
-------------------------

I've just discovered https://issues.apache.org/jira/browse/IO-453

The code that uses file.length() has already been removed in preparation for the 2.5 release.

> 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()}}.
