public class Main<T> {
  private static final String fmt = "%24s: %s%n";

  <E extends RuntimeException> T genericThrow(T t) throws E {
    return t;

  public static void main(String... args) {
    try {
      Class<?> c = Class.forName("Main");
      Method[] allMethods = c.getDeclaredMethods();
      for (Method m : allMethods) {
        Type gpType = m.getGenericReturnType();

    } catch (ClassNotFoundException x) {
