    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.

  2. ,

    If JVM throws ClassNotFoundException the class is not found in classpath. It means that something is not configured correctly. So check the relevant class is in the classpath. If the class is packaged into a jar, the jar should also in the classpath.
