为什么执行器服务接口不实现自动关闭?

						未能调用线程执行程序将导致应用程序永不终止。shutdown()
关闭执行器服务的最佳实践是:
ExecutorService service = null;
try {
  service = Executors.newSingleThreadExecutor();
  // add tasks to thread executor
  …
} finally {
  if (service != null) service.shutdown();
}
既然Java知道试用资源的概念,如果我们能做到这一点,那不是很好吗?
try (service = Executors.newSingleThreadExecutor())
{
  // add tasks to thread executor
  …
}
