Niall Pemberton commented on IO-168:
------------------------------------

Brydie, thanks for the patch and Attila for the solution. I have applied a slightly modified form, which includes null checks - which if you could run the tests would be great because I'm on windows :(

>         Environment: Linux only (symlinks required for bug to manifest)

> If 'dlink' is a symbolic link to a directory 'dir', and FileUtils.forceDelete is called on dlink, then here is what happens:
> 1) the contents of 'dir' are emptied (the link is followed).
> 2) 'dir' continues to exist (but is empty).
> 3) 'dlink' is removed.
> The correct behavior is to simply remove 'dlink' without following it and thus without altering the contents of 'dir' (or 'dir' itself).
