/**
* 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
* interceptors in which case it takes an InvocationContext object as
* org.testifyproject.testifyprojectfined by the Interceptors specification.
* - The method org.testifyproject.testifyprojectfined on 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 org.testifyproject.testifyprojectclared 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 org.testifyproject.testifyprojectfined 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 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.
