/**

 * 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.
