Revolutionizing Java-based Applications with GraalVM.
summary
GraalVM replaces the C2 compiler and offers two Java modes: drop‑in JDK with its Graal compiler for JIT performance and native-image AOT that produces platform binaries with prepopulated heap. Micronaut and Spring (Spring Native) integrate tightly; Micronaut demo drops startup from ~3.3s to ~0.1s, Alibaba moves a huge app from ~60s to ~3s. Tooling includes a tracing agent that emits reflection/config metadata, a metadata repo, quick build mode, UPX compression and cross‑platform via Gluon Substrate; GC options include 0gc.
