Indicates that the container has rejected a request because a concurrent request is associated with the same conversation context.

The container ensures that a long-running conversation may be associated with at most one request at a time, by blocking or rejecting concurrent requests. If the container rejects a request, it must associate the request with a new transient conversation and throw an exception of type BusyConversationException from the restore view phase of the JSF lifecycle.

CDI Lite implementations are not required to provide support for conversations.
