JEP 544 proposes ahead-of-time (AOT) code compilation for the HotSpot JVM to improve startup and warmup times by compiling application code to native code during a training run and caching it for production use. If workloads change dynamically, the system regenerates native code on-the-fly, combining the best of AOT and JIT compilation without requiring code or configuration changes.
Background
Java applications have historically faced criticism for slow startup times compared to native languages. This JEP extends the existing AOT cache workflow introduced in JEP 483 and JEP 515 to include method-level optimization, creating a hybrid AOT/JIT compilation approach.
