summary

Shows a practical pipeline that upgrades Java apps end-to-end: Renovate opens PRs (9 in the Quarkus demo), CI (GitHub Actions) runs builds, OpenRewrite rewrites JavaX→Jakarta (about 90% automated, claims 20M LOC in ~20 minutes) and applies recipes for JUnit/log4j migrations, then a container IDE (Red Hat Developer Sandbox / DevSpaces) lets developers fix remaining failing tests and commit, and SBOMs are sent to Dependency-Track so vulnerability counts drop and compliance evidence exists.
