/**
* The <code>PreDestroy</code> 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 <code>PreDestroy</code> 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 <code>PostConstruct</code> annotation except the Java EE application
* client. The method on which the <code>PreDestroy</code> annotation is applied
* must fulfill all of the following criteria:
* <ul>
* <li>The method must not have any parameters except in the case of
* interceptors in which case it takes an <code>InvocationContext</code> object
* as defined by the Interceptors specification.</li>
* <li>The method defined on an interceptor class or superclass of an
* interceptor class must have one of the following signatures:
* <p>
* void &#060;METHOD&#062;(InvocationContext)
* <p>
* Object &#060;METHOD&#062;(InvocationContext) throws Exception
* <p>
* <i>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.</i></li>
* <li>The method defined on a non-interceptor class must have the following
* signature:
* <p>
* void &#060;METHOD&#062;()</li>
* <li>The method on which PreDestroy is applied may be public, protected,
* package private or private.</li>
* <li>The method must not be static.</li>
* <li>The method should not be final.</li>
* <li>If the method throws an unchecked exception it is ignored by the
* container.</li>
* </ul>
