During May 2025, this developer updated the Jetty integration documentation in the spring-projects/spring-framework repository to support Jetty 12 compatibility for WebFlux applications. They replaced references to the deprecated JettyHttpHandlerAdapter with JettyCoreHttpHandlerAdapter, ensuring the documentation accurately reflects the new Jetty 12+ API. Their work included adding explicit deprecation notes and migration guidance, which helps users transition smoothly and reduces upgrade friction. Using Java, Kotlin, and adoc, the developer focused on documentation hygiene and API adapter migration. The contribution addressed long-term maintenance needs, though it was limited in scope to a single feature and did not involve bug fixes.
