java-upgrade

name	java-upgrade
description	Use when upgrading a Java service to the latest Java LTS (target newest — e.g. Java 25; fall back to 21/17 only if a dependency blocks it), performing the associated framework upgrade (Spring Boot 2→3, javax→jakarta), and containerising the result for ECS/EKS. Covers upgrade tooling (OpenRewrite, jdeps, jdeprscan, Maven/Gradle toolchain), the common Java 8→17/21/25 breakages, the containerisation arc, and — when a managed transformation service (e.g. AWS Transform) is NOT permitted — the prescriptive, group-by-group, build-verified language-native upgrade path (see references/prescriptive-language-native-upgrade.md). Triggers on Java upgrade, JDK upgrade, LTS upgrade, Spring Boot upgrade, jakarta migration, OpenRewrite, jdeps, jdeprscan, containerise Java, Dockerfile for Java, Corretto.

Java Runtime/Framework Upgrade + Containerisation

Primary objective: upgrade a Java service to the latest Java LTS the stack supports (target the newest LTS — e.g. Java 25; fall back to 21 or 17 only if a dependency blocks it), including any needed framework upgrade, and run it as a container on the target platform (ECS/EKS or another the user specifies), containerising only if it isn't already. Decomposition is a stretch target handled separately (see the AI-DLC workflow). Region, platform, and tooling are discovered/decided via the Environment, Region & Tooling section of the AI-DLC workflow.
