Andrew Robinson commented on TRINIDAD-788:
------------------------------------------

0 byte files are very valid, especially on a unix based platform. There are many times that a file by its existence implies meaning. Take for example "~/.config/xserver-xgl/disable", if this file is present, xgl mode of the linux X server is disabled for that user. The file should be empty. This is just one small example.

If an application doesn't want to support 0 byte files, it should use a validator or actionListener method to check the length.

This is different from a blank string in EditableValueHolder. In this instance, the user intentionally uploaded a file with 0 bytes.

I strongly recommend reverting this fix.

> JSF Spec answers this question:
> "Is an empty String (length 0) equal to "no String" (ie. null)?"
> with yes
> (see required on EditableValueHolder interface)
> the inputFile component should also handle empty files (0 bytes) an no file
