We've recently switch our builds from Java 8 to Java 17, and we see some Failsafe tests failing with messages such as these:

However, the class in question does exist in the classpath. We've tried updating the tests to the latest JUnit 4 and 5 versions, but we see the same issue on each.

However, it I build the latest master branch of maven-surefire-plugin locally, and switch to this M6-SNAPSHOT, then the classpath loading works correctly.

When will a new release of the plugin be pushed? Do you know which change since M5 fixed this class loading issue on Java 17?

Thanks
