It should be size_t, and it is size_t in tip, but it is int in jdk17, and I did not want to go down the rabbit hole of changing this and all the dependencies, and thereby risk to introduce funny bugs. The code is made specifically to not overflow int, and it even checks that. I believe we should be good.
