Review comment:
It couldn't be null normally, but `spotbugs` complains about it. (If any
path is `/` path, parent is `null`).
But using `threadRootDir()` instead of using `getParent()` call -- what you
suggested -- solves this problem as spotbugs shouldn't complain about it any
more.
I am updating this...
