Java:泛型和继承

我正在构建一个类引导程序,用于引导实现可引导的其他类。

// interface that every class must implement that needs to be bootstrapped
class Bootstrappable implements Runnable {
  public foo();
}

class MyApp implements Bootstrappable {
  public void foo() {}
}

class Bootstrap {
  private Bootstrappable instance;

  public bootstrap(Class<Bootstrappable> b) {
    instance = b.newInstance();
    ...
  }
}

new Bootstrap().bootstrap(MyApp.class);

类型bootstrap中的方法bootstrap(类Bootstrappable)不适用于参数(类MyApp)
