/** 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 bridge from
 * the bridge request scope. This method complements one using
 * javax.annotation.PreDestroy to allow the object to release resources
 * that it has been holding. It exists because the existing
 * javax.annotation.PreDestroy method must be ignored as it is called
 * by the container even though the bridge continues to manage the object in its
 * request scope. The method on which the PreDestroy annotation is applied MUST
 * fulfill all of the following criteria - The method MUST NOT have any parameters -
 * The return type of the method MUST be void. - The method MUST NOT throw a checked
 * exception. - The method on which PreDestroy is applied MUST be public. - The
 * method MUST NOT be static. - The method MAY be final. - If the method throws an
 * unchecked exception it is ignored.
