Thank you for your answer. I have looked at the source code myself and I did not find anything that could be an issue. Still, something tells me this is not the only place where things can go wrong. Hopefully, different JVMs (different vendors) in the same cluster will not be a case for us.

I would think that if a vendor is breaking the spec you could run a bunch of known Strings and compare to the official results. Be sure to run some long ones. Back in Java's early days the hashCode method only considered the first 16 (maybe 32?) characters. I could see a vendor trying to win a benchmark by doing similar.

Good advice, thanks for sharing it. I believe for the current matter we will stick with Oracle's JVM, although that knowledge might prove quite useful one day. Having thoughts on it, such "performance gain" may cost a lot of undesired and unpredictable behavior. Wonder if a JVM vendor out there could fall into that category
