> DiskChecker#checkDirs should check null pointer for the return value from
> File#listFiles. Based on the document for File#listFiles at
> https://docs.oracle.com/javase/7/docs/api/java/io/File.html#listFiles() :
> {code}
> Returns null if an I/O error occurs.
> {code}
> So it will be good to check null pointer and throw DiskErrorException if it
> is null.
