Clarify contextual reference validity to a bean with a normal scope in Java SE

In Java SE, a user might be tempted to share a contextual reference for a normal scoped bean (client proxy) between multiple "deployments" of a single application, e.g.:

1. start CDI container
2. get a reference
3. stop CDI container
4. start CDI container again and try to use the stored reference.

I believe such a reference should not be valid after an application stopped (contexts are destroyed, etc.). Right now, it seems to be undefined.
