I could reproduce the issue with `Files.createDirectories` on a macos with a trivial program. It appears to be because of the use of `NOFOLLOW_LINKS` here https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/nio/file/Files.java#L808. To me this appears to be something that either needs to be clarified in the the `Files.createDirectories` API or addressed/fixed there. I have asked for inputs on this from others who have more knowledge of this area. ------------- PR: https://git.openjdk.org/jdk/pull/10266
