Review comment:
The system property is JVM level. If we don't unset the config, later
tests will be using this config. Maybe there are no tests using the config yet.
But I suggest, as a good practice, we also unset the config to make unit tests
isolated, ensuring other tests won't be impacted by this test's configs.
