/**

 * The PostConstruct 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 PostConstruct MUST be invoked even

 * if the class does not request any resources to be injected. Only one

 * method can be annotated with this annotation. The method on which the

 * PostConstruct 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 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 <METHOD>(InvocationContext)

 * <p>

 * Object <METHOD>(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 <METHOD>()

 * </li>

 * <li>The method on which PostConstruct 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 MAY be final.</li>

 * <li>If the method throws an unchecked exception the class MUST NOT be put into

 * service except in the case of EJBs where the EJB can handle exceptions and

 * even recover from them.</li></ul>
