> I might just be getting old, but I'm positive a professor and I broke the Java hash function wide open in college using this method, yet my 15 minute attempt to replicate this result gives me an image which looks like a good hash function would result in: white noise. Is it possible Java has updated the string hashing function since you've done this?
