      Description

      Many processes that call listStatus() expect to handle IOException, but instead are getting runtime error NullPointerException, if the directory being scanned is visible but no-access to the running user id. For example, if directory foo is drwxr-xr-x, and subdirectory foo/bar is drwx------, then trying to do listStatus(Path(foo/bar)) will cause a NullPointerException.
