    - One of the disadvantages of Guice is it requires constructor annotation like `@Inject`. This is less convenient if you are using third-party libraries, which cannot add such annotations. So you often need to write many provider binding modules to use third-party classes.
    - Airframe has provider bindings in `bind { d1: D1 => new X(d1) }` syntax so that you can directly call the constructor of third-party classes. No need to implement object binding modules.
     - [Guice Bootstrap](https://github.com/embulk/guice-bootstrap) is an extension of Guice to support life-cycle management using `@PostConstruct` and `@PreDestroy` annotations.
