/**
 * 
 * Defines an interceptor method that interposes on timeout methods. The method must take a single parameter of type
 * {@link javax.interceptor.InvocationContext} and have a return type {@link java.lang.Object}. The method must not be
 * declared as abstract, final, or static.
 * 
 *
 *  * @AroundTimeout
 * public Object interceptTimeout(InvocationContext ctx) throws Exception { ... }
 * 
 *
 * 
 * AroundTimeout methods may be declared in interceptor classes, in the superclasses of interceptor classes, in
 * the target class, and/or in superclasses of the target class.
 * 
 *
 * 
 * A given class must not declare more than one AroundTimeout method.
 * 
 *
 * 
 * An AroundTimeout method can invoke any component or resource that its corresponding timeout method can
 * invoke.
 * 
 *
 * 
 * {@link javax.interceptor.InvocationContext#getTimer()} allows any AroundTimeout method to retrieve the timer
 * object associated with the timeout.
 * 
 *
 * 
 * In general, AroundTimeout method invocations occur within the same transaction and security context as the
 * timeout method on which they are interposing.
 * 
 *
 * 
 * AroundTimeout methods may throw any exceptions that are allowed by the throws clause of the timeout method
 * on which they are interposing. They may catch and suppress exceptions and recover by calling
 * {@link javax.interceptor.InvocationContext#proceed()}.
