/**
* The PreDestroy annotation is used on methods as a callback notification to
* signal that the instance is in the process of being removed by the
* container. The method annotated with PreDestroy is typically used to
* release resources that it has been holding. This annotation MUST be
* supported by all container managed objects that support PostConstruct
* except the application client container in Java EE 5. The method on which
* the PreDestroy 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 InvocationContext 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 PreDestroy is applied MAY be public, protected,
* package private or private.
* - The method MUST NOT be static.
* - The method MAY be final.
* - If the method throws an unchecked exception it is ignored except in the
* case of EJBs where the EJB can handle exceptions.
