Note that there are actually two possible results one could expect:

• the first request ends before the conversation is associated with the second request -> NonexistentConversationException (this should work even now)
• the first request ends after the conversation is associated with the second request -> IllegalStateException because of Conversation.end() (see also http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#conversation)
