Spoiled For Choice: Limit Your Options
summary
Argues that consolidating libraries cuts security and maintenance pain by applying OpenRewrite migration recipes to real code bases, not slides. Shows automated migrations between logging frameworks (SLF4J ↔ Log4j), testing frameworks (various → JUnit Jupiter), and nullability annotations → JSR‑305/JSR‑305 like JSpecify and updates dependency versions. Runs recipes on ~1,000 repositories producing thousands of changes and auto‑opened pull requests, and demos org‑scale orchestration via app.modern.io to migrate many services at once.
