Adopt Open J9 for Spring Boot performance!
summary
Adopt OpenJ9 replaces HotSpot with a one-line change to the base image and shows concrete wins: Docker memory drops from 455MB→160MB (~60% reduction) for a Spring Boot PetClinic run, warmed images start in ~6–7s, and share classes plus AOT/JIT caches eliminate repeated compilation. Demonstrated tools and configs include AdoptOpenJDK/OpenJ9 Docker images, -Xquickstart and shared class cache flags, multi-stage Docker builds and the Boost Maven plugin to produce lean images. Results prioritize lower footprint, faster startup, and simpler adoption.
