JDK-8032220 - Files.createDirectories throws exception with confusing message for root directories that exist
Description
mkdir(2) on Linux [1] is permitted to fail with either EACCES or EEXIST according to POSIX [2]. In [3] the possibility was discussed of not throwing AccessDeniedException on Linux when mkdir fails with EACCES and the Path is to a directory. This should be investigated.
