Managed beans LifeCycle annotations @PostConstruct and @PreDestroy

 Based on the article here http://www.bleedyellow.com/blogs/erik/entry/xpages_are_not_modern?lang=cs_cz  the XPages are based on JSF 1.2  .... what means that we should be able to use annotaions on managed beans to inject the beans lifeCycle.
 
I have found the following information (below) in the docs. But annotations do not work for me in managed beans. I have tried both @PostConstruct and   @PreDestroy but nothing happened. Is there anyone who has experience with this?
 
 
[Life Cycle Annotations]
Starting with JSF 1.2, you can specify managed bean methods that are automat-ically called just after the bean has been constructed and just before the bean 
goes out of scope. This is particularly convenient for beans that establish con-nections to external resources such as databases. 
Annotate the methods with @PostConstruct or @PreDestroy, like this:
 
public class MyBean {
   @PostConstruct
   public void initialize() {
      // initialization code
   }
   @PreDestroy
   public void shutdown() {
      // shutdown code
   }
   // other bean methods
}
These methods will be automatically called, provided the web application is 
deployed in a container that supports the annotations of JSR (Java Specification 
Request) 250 (see http://www.jcp.org/en/jsr/detail?id=250).

Release 9.0.1 FP8

We are 6 years latter and I am still not able to make it work. Or am I doing anything wrong?

To be clearly understood: @PostConstruct annotation can be used but the method is not called after the bean is constructed.
