+/**
+ * The <code>PostConstruct</code> annotation is used on a method that needs to
+ * be executed after dependency injection is done to perform any initialization.
+ * This method must be invoked before the class is put into service. This
+ * annotation must be supported on all classes that support dependency
+ * injection. The method annotated with <code>PostConstruct</code> must be
+ * invoked even if the class does not request any resources to be injected. Only
+ * one method in a given class can be annotated with this annotation. The method
+ * on which the <code>PostConstruct</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 PostConstruct 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 PostConstruct
+ * 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 the <code>PostConstruct</code> annotation is applied
+ * may be public, protected, package private or private.</li>
+ * <li>The method must not be static except for the application client.</li>
+ * <li>The method should not be final.</li>
+ * <li>If the method throws an unchecked exception the class must not be put
+ * into service except in the case where the exception is handled by an
+ * interceptor.</li>
+ * </ul>
