I don't think the exchange so far has clearly established the issue. It is likely related to the permissions on /tmp on this system but maybe there is a umask setting in the picture too. In any case, I think it's better if this test uses the work directory rather than /tmp.  You'll need to change the static initializer where it first tests if underlying file store support POSIX file permissions. Also in the op method it would be nicer if you used something like `Path dir = Path.of(".");` so you have a Path to the directory for the 4 places that use it.
