Upgrading from #java 21 to #java 25 was easy. Only had to fix a Lombok issue. All in all it cost me a couple of hours (less then half a day): some discussion, change build plan, change Maven POM, fix issue, run @openrewrite.github.io so we use the new language features and PR review and merge.

A client was about to drop $3M on new hardware for K8s. 😰

Until Kevin Brockhoff’s team wrote a custom OpenRewrite recipe + tied it into their observability platform.

Turns out the real issue wasn’t hardware at all...it was large over-provisioning in container configs.
