SimpleStrategy creates a list of endpoints by iterating over the set of all configured endpoints for the given token, until we reach keyspace replication factor. There is a trivial coding bug when we first add at least one endpoint to the list, and then compare list size and replication factor. If RF=0 this never yields true. Fix by moving the RF check before at least one endpoint is added to the list. Cassandra never had this bug since it uses a less fancy while() loop.
