/**
* The PostConstruct annotation is used on a method that needs to be executed
* after dependency injection is done to perform any initialization. This
* method MUST be invoked before the class is put into service. This
* annotation MUST be supported on all classes that support dependency
* injection. The method annotated with PostConstruct MUST be invoked even
* if the class does not request any resources to be injected. Only one
* method can be annotated with this annotation. The method on which the
* PostConstruct annotation is applied MUST fulfill all of the following
* criteria -
- The method MUST NOT have any parameters except in the case of EJB
* interceptors in which case it takes an InvocationC ontext object as
* defined by the EJB specification.
* - The return type of the method MUST be void.
* - The method MUST NOT throw a checked exception.
* - The method on which PostConstruct is applied MAY be public, protected,
* package private or private.
* - The method MUST NOT be static except for the application client.
* - The method MAY be final.
* - If the method throws an unchecked exception the class MUST NOT be put into
* service except in the case of EJBs where the EJB can handle exceptions and
* even recover from them.
