App Modernization of Java applications.
summary
GitHub Copilot App Modernization assesses a Java repo with appcat and open rewrite plus LLMs, creates a plan, then applies automated commits that upgrade runtime (example Java 8 to 21), fix CVEs (Apache Commons Lang bumped), and refactor code — the demo shows it changing 43 Java files and producing a branch with build and test runs that pass. It also writes Dockerfiles and Bicep templates and can deploy to Azure Container Apps while using guardrails to avoid LLM drift.
