`dir` and `cwd` always at the different path, but maybe at the same volume. So check if they are at the some FileStore and re-throw `AtomicMoveNotSupportedException`.


Below is the actual path when run this test.

cwd: /home/yansendao/git/jdk-ysd/build/manual-run/jt-work/scratch
dir: /home/yansendao/git/jdk-ysd/build/manual-run/jt-work/scratch/name7513119775509255640
