I have tried to run the test case you’ve provided, and all tests are passing: [INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running net.test.BidTest Feb 03, 2023 9:12:26 PM org.hibernate.validator.internal.util.Version <clinit> INFO: HV000001: Hibernate Validator 8.0.0.Final [INFO] Tests run: 3, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.122 s - in net.test.BidTest [INFO] [INFO] Results: [INFO] [INFO] Tests run: 3, Failures: 0, Errors: 0, Skipped: 0 I’ve only added the surefire plugin to your project to run the tests from maven: <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>3.0.0-M8</version> </plugin> </plugins> </build> Could you try doing so (adding the surefire plugin and running the maven build in the terminal) to eliminate any IDE-related issues? If you still see the error after that - it might be that a problem comes from a particular version of the JDK you are using. Could you provide that? Thanks!
