| /** |
| * 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 <METHOD>(InvocationContext) |
| * <p> |
| * Object <METHOD>(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 <METHOD>() |
| * </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> |
