-------------------------------

             Summary: FileUtils.readFileToString() can immediately return empty 
string if file length is zero
                 Key: IO-486
                 URL: https://issues.apache.org/jira/browse/IO-486
             Project: Commons IO
          Issue Type: Improvement
            Reporter: Viktor Isaev


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()}}.
