  EqualsVerifier 4.5 is out! It adds a new check: it fails if you use java.net.URL's equals() method, because this will make a network call that can be flaky. (Convert to java.net.URI instead.) You can suppress this with a new Warning though. Check it out: https://github.com/jqno/equalsverifier/blob/main/CHANGELOG.md #java
