Web Reference: Jan 15, 2026 · Once the Java 21 → 25 migration is complete and stable, the next logical step is upgrading Spring Boot itself. This is where OpenRewrite delivers its highest ROI. Jan 5, 2026 · Currently, our backend project (Web Flux+Kotlin Coroutines/R2dbc/PostgreSQL) worked well when upgraded to Spring Boot 4 with Java 21/Kotlin 2.3. Recently we were trying to upgrade Java to 25, about 100 test cases are failed with the famous Out Of Memory error. Using the latest LTS release of Java is encouraged. Spring Boot applications can also be developed using Kotlin where v2.2 or later must be used. If you’re using GraalVM’s native-image, v25 or later must be used. Spring Boot 4 is based on Jakarta EE 11 and requires a Servlet 6.1 baseline.
