when a given MethodInvocation argument represents static method:
> h3. Technical Info
> [http://shiro.apache.org/static/1.2.2/apidocs/src-html/org/apache/shiro/aop/DefaultAnnotationResolver.html#line.62]:

return null causing the following chained call {{getClass()}} fail with NullPointerException.
