---------------------------------------

             Summary: 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


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...
