Gabriel Reid updated CRUNCH-428:
--------------------------------
Attachment: CRUNCH-428.patch
Here's the patch. I'm going to commit this right away because it's a simple bug
and (as far as I can see) there's nothing that could get (more) broken by this
change.
> Disallow empty list of paths for file inputs

> Key: CRUNCH-428

>
> There is currently no checking on the number of input paths supplied in a
> list to FileSourceImpl and its subclasses. This can lead to a confusing error
> when the empty list is deserialized from CrunchInputs, as an attempt is made
> to create a Path from an empty string.
> The various paths that construct FileSourceImpl subclasses should defensively
> protect against creating a file source with an empty list of paths.
