Object factory implementation. This method returns a Context proxy that is only able to handle a lookup operation for an atomic name of a security domain.

 public Object invoke(Object obj,
    Method method,
    Object[] args) throws Throwable 
{
         TimedCachePolicy cachePolicy = new TimedCachePolicy(defaultCacheTimeout,
            true, defaultCacheResolution);
         cachePolicy.create();
         cachePolicy.start();
         return cachePolicy;
}

This is the InvocationHandler callback for the Context interface that was created by out getObjectInstance() method. All this does is create a new TimedCache instance.
