In the explanation of option 5 "Callback methods can't be final or static".
Actually, according to the Java 6 API,
@PostContruct and @PreDestroy may be final;
@PostActivate and @PrePassivate must not be final or static.

Intercepters are governed by Interceptors specification and on page 9 of Interceptors 1.1 specification, it clearly says, "A lifecycle callback interceptor method must not be declared as final or static."
