Jenkins _does_ have them, I showed tests half a year ago and in this thread too. Actually _any_ hash has them it is just a matter of time to find one.
I think you misunderstood me. If you are trying to DoS me from outside with a hash collision attack, you are trying to feed me packets that fall into the same hash bucket. The Jenkins hash does not have to be artifact-free, and does not have to be cryptographically strong. It just has to do a passable job of mixing a random salt into the tuple, so you don't know which string of packets to feed me in order to fill one (or a few) of my buckets. XORing salt into a folded tuple doesn't help; it just permutes the buckets.
