Let me give an example. Someone defines a service A, which supports remote invocation. There is no dependency between service A and the EJB container (Service B), because it doesn't make sense (they have nothing to do with each other). Then instance SFSB Foo of Service B *dynamically* decides to call service A during an invocation. Then during "graceful" shutdown, service A is stopped first.

The point is that runtime callflow is orthoginal to service dependencies.
