Thank you again Simon!
> IOUtils methods taking Iterable<? extends Path> try to delete every element
> of the path

> Key: LUCENE-6051
> URL: https://issues.apache.org/jira/browse/LUCENE-6051
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/other
> Reporter: Simon Willnauer
> Priority: Blocker
> Fix For: 5.0, Trunk
>
> Attachments: LUCENE-6051.patch
>
>
> We have two methods in IOUtils
> {code}
> public static void deleteFilesIgnoringExceptions(Iterable<? extends Path>
> files);
> public static void deleteFilesIfExist(Iterable<? extends Path> files) throws
> IOException
> {code}
> 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...
