tip

This means you're missing a class that Java needs for this program. Check if you're not missing the jsr305-1.3.7.jar from your classpath, it's the jar that contains the class javax.annotation.Nullable.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
