Since $analyzer is declared private, accessing it with static will lead to errors in possible sub-classes; you can either use self, or increase the visibility of $analyzer to at least protected.

            static::$analyzer = new AnnotationsAnalyzer();
        }
        return static::$analyzer;
    }
