Java gets called legacy by people who have not looked at it recently, usually while running on a stack that will be someone else's legacy in four years.
Spring Boot is the reason it stayed relevant. Convention over configuration, production concerns like health checks, metrics and externalised config handled as first-class features, and an ecosystem that has already solved most of what an enterprise system needs.
We use it for the systems that must not fall over — payments, order processing, integration backbones — and we modernise existing Java estates incrementally: strangler-pattern migration off the monolith, tests added around the parts nobody dares touch, and a JDK upgrade path that does not require a big-bang weekend.
Boring, well understood and still running in ten years is a feature.
What is the oldest system you rely on but nobody wants to open?
