getAnnotationParameter

public static <T> T getAnnotationParameter(javax.lang.model.util.Elements elements,
                                           javax.lang.model.element.Element element,
                                           Class<?> annotationType,
                                           String parameterName,
                                           Class<? extends T> expectedReturnType)

Gets an annotation parameter from an annotation. Usually you can just get the parameter directly, but if the parameter has type Class it doesn't work, because javac doesn't load classes in the normal manner.
