> While testing Disk Fail Inplace, we encountered lots of NPE from
> Dir.listFiles API. This API can return null when Dir is not directory or disk
> is bad. I am proposing to have a File Util which can be used consistently
> across to deal with disk issues. This util api will do the following:
> 1. When error happens it will throw IOException
> 2. Else it will return empty list or list of files.
> Signature:
> File[] FileUtil.listFiles(File dir) throws IOException {}
> This way we no need to write wrapper code every where. Also, API is
> consistent with the signature.
