> Why then don't people write in Java for performance?
They do. Just like people write for PyPy for performance.
The only challenge to Java's performance is from languages without dynamic GC and with detailed static type information: C, C++, Rust. Even then, Java is usually "only" half the speed.
And AOT is coming for fast start-up, not good steady-state performance.
