/**
 * The PreDestroy annotation is used on a method 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 the use of
 * the PostConstruct annotation except the Jakarta EE application 
 * client. 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
 * interceptors in which case it takes an InvocationContext
 * object as defined by the Interceptors specification.
 * The method defined on an interceptor class or superclass of an
 * interceptor class must have one of the following signatures:
 * 
 * void <METHOD>(InvocationContext)
 * 

 * Object <METHOD>(InvocationContext) throws Exception
 * 

 * Note: A PreDestroy interceptor method must not throw application
 * exceptions, but it may be declared to throw checked exceptions including
 * the java.lang.Exception if the same interceptor method interposes on
 * business or timeout methods in addition to lifecycle events. If a
 * PreDestroy interceptor method returns a value, it is ignored by
 * the container.
 * 
 * The method defined on a non-interceptor class must have the
 * following signature:
 * 
 * void <METHOD>()
 * 
 * The method on which PreDestroy is applied may be public, protected,
 * package private or private.
 * The method must not be static.
 * The method should not be final.
 * If the method throws an unchecked exception it is ignored by
 * the container.
