JDK8とJDK11でJavaアノテーションの値を読み取る方法は?

import io.cucumber.java.en.When;

public class Sof {

    private static final Logger log = LoggerFactory.getLogger(Sof.class);

    @When(value = "I update text {string} with {string}(\\?)")
    public static void main(String[] args) {
        Class c = Sof.class;
        Method[] methods = c.getMethods();
        Method method = null;
        for (Method m : methods) {
            if (m.getName().equals("main")) {
                method = m;
            }
        }
        Annotation stepAnnotation = method.getAnnotation(When.class);
        Object as[] = { "a", "b" };
        Matcher matcher = Pattern.compile("value=(.*)\\)").matcher(stepAnnotation.toString());
        if (matcher.find()) {
            log.info("---> " + stepAnnotation.annotationType().getSimpleName() + " " + String.format(matcher.group(1).replaceAll("\\{\\S+\\}", "{%s}").replace("(\\?)", ""), as));
        } else {
            System.err.println("error");
        }
    }

}

/!\実は注釈の種類がわかりません@When。これは、io.cucumber.java パッケージ内の任意のインターフェースにすることができます

結果JDK8:

---> When I update text {a} with {b}

結果 JDK11 (余分な引用): (stepAnnotation.toString()違います!)

---> When "I update text {a} with {b}"

編集 openjdk11し、oraclejdk11javadoc を尊重しない:

/**
 * Returns a string representation of this annotation.  The details
 * of the representation are implementation-dependent, but the following
 * may be regarded as typical:
 * <pre>
 *   &#064;com.acme.util.Name(first=Alfred, middle=E., last=Neuman)
 * </pre>
 *
 * @return a string representation of this annotation
 */
String toString();
