      Longer or more elaborate examples are probably better suited
      to the package docs.
   9. Test methods are a good place to add Javadoc, because you can use it
      to succinctly describe e.g. preconditions, actions and expectations
      of the test, more easily that just using the test name alone. Please
      consider documenting your tests in this way.
   10. Sometimes you shouldn't add Javadoc:

    Preconditions.checkNotNull(task, "task must not be null!");
    Preconditions.checkNotNull(result, "result must not be null!");
    return delegate.submit(task, result);
  }

  @Override
  public ListenableFuture<?> submit(Runnable task) {
    Preconditions.checkNotNull(task, "task must not be null!");
    return delegate.submit(task);
  }

  @Override

    Preconditions.checkNotNull(task, "task must not be null!");
    Preconditions.checkNotNull(result, "result must not be null!");
    return delegate.submit(task, result);
  }

  @Override
  public ListenableFuture<?> submit(Runnable task) {
    Preconditions.checkNotNull(task, "task must not be null!");
    return delegate.submit(task);
