Steps to reproduce

JaCoCo version: 0.8.2
Tool integration: Maven/SonarQube

Expected behaviour

We created a @Generated annotation with retention policy CLASS:

@Target({ElementType.CONSTRUCTOR, ElementType.METHOD, ElementType.FIELD, ElementType.TYPE})
@Retention(RetentionPolicy.CLASS)
public @interface Generated {
    String by() default "";
}

SonarQube is working fine ignoring new methods for coverage annotated with that annotation.
We expect to have this working fine also when used on class level.

Actual behaviour

But instead usage on class level is just ignored. All the lines are still reported to need coverage.

Even worse: When used on class and method level the method level annotation stops working also.
