JEP 544: Ahead-of-Time Code Compilation

JEP 544 proposes to improve Java application startup and performance by compiling code to native code during a training run and caching it for use in production, while still allowing dynamic JIT compilation if workloads change. The enhancement aims to enable applications to reach peak performance faster without requiring code changes or new AOT workflows, initially supporting AArch64 and x64 architectures. This hybrid approach combines ahead-of-time (AOT) and just-in-time (JIT) compilation to balance fast startup with adaptability to changing workloads.
