Description

We have two methods in IOUtils

 public static void deleteFilesIgnoringExceptions(Iterable<? extends Path> files);

 public static void deleteFilesIfExist(Iterable<? extends Path> files) throws IOException

if you call these with a single Path instance it interprets it as Iterable<Path> since Path implements Iternable<Path> and in-turn tries to delete every element of the path. I guess we should fix this before we release. We also need to check if there are other places where we do this... it's nasty...
