Self-contained Native Binaries for Java with GraalVM
summary
GraalVM Native Image compiles Java ahead-of-time into a platform native binary that drops the JVM, resulting in 20–40× startup and examples showing a 41× faster startup for Spring PetClinic and 35% RAM reduction versus HotSpot (profile‑guided builds can also raise peak throughput). Build performs reachability analysis and limits reflection so metadata or community metadata is often required. Binary inspection and profiling use Linux tools like psrecord, perf / perf record and flame graphs; images include SBOMs, can be 13 MB (from‑scratch) or ~4 MB with UPX. Recommended for ~0.5–1 GB heaps and cloud frameworks (Spring, Quarkus, Micronaut, Helidon).
