        Parameters:
        element - the element on which to search for the annotation
        annotationType - the annotation type of need to search
        Returns:
        the searched annotation type

        If the annotation's annotationType is not annotationType, then to find the first annotation of annotationType that is either directly present, meta-present, or indirectly present on the supplied element.
        Type Parameters:
        A - the searched annotation type
        Parameters:
        annotation - annotation
        annotationType - the annotation type of need to search
