We're on 3.9.0, and the migration 3.8 -> 3.9 was extremely painless, we had like 4 source change in whole rudder.io code, and among them it even caught a real bug in our code. I think it was the first one so easy. Perhaps after 2.12 -> 3, everything will look easy, though

Project Crema is gaining features every day, it uses JVMCI with Graal as JIT compiler... the VM, the compiler, all written in Java. The tradeoff: drop optimizations specific to closed world, but with the JIT (Graal), dynamically loaded code can be even faster (vs AOT) at runtime.

Project Crema will shift AOT-compilation from a binary switch (current closed world) into a continuous knob ... fine-grained control of what is AOT-compiled while keeping full compatibility with dynamically loaded classes e.g. full reflection. Best of both worlds!
