 The `src/test` folder contains, apart from the regular `java` folder, some version-specific `javaXX` folders that target specific JDKs. For instance, the `src/test/java16` folder contains unit tests that test things related to records. A Maven profile automatically picks up these folders if the JDK that runs the tests has at least that version. `nl.jqno.equalsverifier.internal.architecture.TestPresenceTest` checks that the tests are indeed picked up when the JDK version matches.
