Going AOT: Everything you need to know about GraalVM for Java applications
summary
Overview of what is actually shown: a Spring Boot app built with GraalVM Java 22 and the Graal native-image tool using the Graal Maven/Gradle plugin, producing a 4.7 MB native binary that starts in 47 ms and serves HTTP endpoints; builds report reachable-types counts and memory per stage and can run on GitHub Actions for cross-platform builds. Reflection and resource handling use shipped JSON configs, a tracing agent, or the centralized “ready for native image” repo. Profile-guided optimization (PGO) and the ML predictor improve peak throughput and memory efficiency, with tests showing up to ~2x throughput per GB around 512 MB when tuned.
