Tools & Tips to Modernize Your Java code with AI
summary
Live demo shows an agent that ingests a JFR file, maps hotspots to known anti‑patterns, edits source, then builds and tests the fixes automatically, cutting a 1s request to ~200ms (~5x) and costing about 10¢ demo cost to run. Tooling includes the ATX CLI, JFR/JDK Mission Control, a Curo CLI workflow that emits dependency maps and leadership reports, OpenRewrite recipes and an Embabel modernizer agent; migrating Java 8→17 yields ~50% memory reduction and the pipeline scales to thousands of apps, not single files.
