/**
* 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:
* <p>
* <ul>
* <li>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.</li>
* <li>The method defined on 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 MAY be final.</li>
* <li>If the method throws an unchecked exception it is ignored except in the
* case of EJBs where the EJB can handle exceptions.</li>
* </ul>
