Sebb resolved IO-293.
---------------------
Resolution: Not A Problem
The patch effectively amounts to inlining the code for IOUtils.toByteArray and
does not save any memory as far as I can tell.
> Reduce memory consumption when reading file into byte[]

>
> Improvement for org.apache.commons.io.FileUtils method
