/**
 * Designates a method on a stateless session bean class, a singleton session bean class, a message driven bean class,
 * or an enterprise bean 2.x entity bean class that should receive enterprise bean timer expirations for that bean.
 * 
 * The method to which the Timeout annotation is applied must have one of the following signatures, where
 * <METHOD> designates the method name:
 *
 *
 * 
 * void <METHOD>()
 * void <METHOD>(Timer timer)
 * 
 *
 * A timeout callback method can have public, private, protected, or package level access. A timeout callback method
 * must not be declared as final or static. Timeout callback methods must not throw application exceptions.
 * 
 * If the bean implements the TimedObject interface, the Timeout annotation can only be
 * applied to the ejbTimeout method.
