I agree with Mark's analysis.
In Jetty the other context attribute would be there, as any code with a
reference to a context is able to set attributes on it.
As Mark says, using a request attribute would be a better way to pass such
attributes between contexts (with the caveat of classloading issues Mark
referred to).
