They were close but unfortunately went too far at being opinionated in solve the issues of using C at the time of Java's inception. Changing this now is Valhalla project which has unknown release date.

Luckily, C# learned from this mistake and made a decision to follow C much closely, having integers as proper primitives and supporting structs since day 1, and only improved since then in this area (JVM needs insane pointer compression and shadow tricks to pack integers to claw back performance, and in .NET "it just works" instead).

I wonder if Cassandra was written in .NET, it wouldn't have such a poor performance (though this can also be showcased by Garnet which beats competition written in C++ and C).
