There are a great many tests that clear system properties in an "AfterClass" or "After" method in a test. But I think this should be unnecessary thanks to SystemPropertiesRestoreRule that is installed at both a test method level and a class/suite level (see SolrTestCaseJ4 and SolrTestCase and search for SystemPropertiesRestoreRule). Can we stop this outdated practice of clearing system properties in tests? Or are there gotchas?
