Answer 1

1. @javax.annotation.PostConstruct is not shipped with Spring, although Spring supports it if it finds it on the classpath. @PostConstruct can be found in Java6, but not in Java5. You can also find it in some EJB3 downloads.

2. registerShutdownHook() is a method on ConfigurableApplicationContext, which is a subtype of ApplicationContext.
