Review Comment:
This is a difference between JUnit4 and JUnit5. The blob server storage
folder (where `tempFileDir` points) has no write permissions at the time of
`close()` is called on master as well, but JUnit4 ignores that and removes the
folder anyways. JUnit5 does not.
JUnit4 list dir for the server storage dir at the point of delete:
```
/var/folders/wp/ccy48gw1255bswh9bx9svxjc0000gn/T/junit5602027938676775669
