* @summary To Test the following assertions in InvovationEvent.
* 1.InvocationEvent when dispatched, should invoke the
* run() method of the Runnable Interface.
* 2.If catchExceptions is false, Exception should be
* propagated up to the EventDispatchThread's dispatch loop.
* 3.If catchExceptions is true, InvocationEvent.getExceptions()
* should return the exception thrown inside thr run() method.
* 4.When InvocationEvent object is posted on to the EventQueue,
* InvocationEvent.dispatch() method should be invoked by the
* EventQueue.
* 5.If the notifier object is not null, notifyAll() of the
* notifier object should be invoked when the run() method returns.
* 6.To test whether the threads are invoked in the right order
* When InvocationEvents are nested.
* 7.The getWhen method should return timestamp which is less than
* current System time and greater than the time before it has
* actually happened
