分析以下Java Annotation类文件时，Sonar会抛出NullPointerException：
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface MyAnnotation
{
String description() default "MyAnnotation";
int order() default Integer.MAX_VALUE;
boolean continueOnFailure() default false;
}

通过我们的Teamcity服务器中的mvn sonar:sonar -X调用Sonar来生成上述堆栈跟踪。
有谁知道如何解决这个问题？
