JEP 544: Ahead-of-Time Code Compilation

JEP 544 introduces an Ahead-of-Time (AOT) cache that stores native code generated during a training run, allowing the HotSpot JVM to start with optimized code and switch to Just-in-Time (JIT) compilation when workloads evolve. The approach requires no code or configuration changes, supports Serial, Parallel, G1 and ZGC collectors, and targets AArch64 and x64 architectures while preserving invisible transitions between AOT and JIT.
