1.35 +/**
1.36 + * The PreDestroy annotation is used on methods as a callback notification to
1.37 + * signal that the instance is in the process of being removed by the
1.38 + * container. The method annotated with PreDestroy is typically used to
1.39 + * release resources that it has been holding. This annotation MUST be
1.40 + * supported by all container managed objects that support PostConstruct
1.41 + * except the application client container in Java EE 5. The method on which
1.42 + * the PreDestroy annotation is applied MUST fulfill all of the following
1.43 + * criteria:
1.44 + * <p>
1.45 + * <ul>
1.46 + * <li>The method MUST NOT have any parameters except in the case of
1.47 + * interceptors in which case it takes an InvocationContext object as
1.48 + * defined by the Interceptors specification.</li>
1.49 + * <li>The method defined on an interceptor class MUST HAVE one of the
1.50 + * following signatures:
1.51 + * <p>
1.52 + * void <METHOD>(InvocationContext)
1.53 + * <p>
1.54 + * Object <METHOD>(InvocationContext) throws Exception
1.55 + * <p>
1.56 + * <i>Note: A PreDestroy interceptor method must not throw application
1.57 + * exceptions, but it may be declared to throw checked exceptions including
1.58 + * the java.lang.Exception if the same interceptor method interposes on
1.59 + * business or timeout methods in addition to lifecycle events. If a
1.60 + * PreDestroy interceptor method returns a value, it is ignored by
1.61 + * the container.</i>
1.62 + * </li>
1.63 + * <li>The method defined on a non-interceptor class MUST HAVE the
1.64 + * following signature:
1.65 + * <p>
1.66 + * void <METHOD>()
1.67 + * </li>
1.68 + * <li>The method on which PreDestroy is applied MAY be public, protected,
1.69 + * package private or private.</li>
1.70 + * <li>The method MUST NOT be static.</li>
1.71 + * <li>The method MAY be final.</li>
1.72 + * <li>If the method throws an unchecked exception it is ignored except in the
1.73 + * case of EJBs where the EJB can handle exceptions.</li>
1.74 + * </ul>
