Jakarta EE 10 - Simplicity for Modern and Lighweight Cloud Applications
summary
Jakarta EE 10 ships (released Sep 22) with a new Core Profile for microservices that targets much smaller runtimes, supports Java SE 11 and 17 (APIs compiled to 11 but tested on 11/17), and enables native-image builds via GraalVM. It adds CDI 4.0 Lite build-time extensions (reflection-free, build-time discovery, beans.xml required for SE), a Java SE bootstrap API for bootable JARs (demo used RESTEasy + JSON‑B), OpenID Connect in Security, multipart REST support, and concrete migration tools (Eclipse Transformer/Tomcat migrator) that worked in the demo.
