The transition of Java EE to the Eclipse Foundation is now complete with the release of the Jakarta EE 8 Platform Specification and the compatible implementations, including Payara Server. The release plan for Jakarta EE 9 is also approved, and will move all the Java EE APIs to the jakarta namespace - providing a future platform for Jakarta EE 10 and beyond.
Jakarta EE has a clear roadmap and open-source future. Attention is now turning to the relationship between Eclipse MicroProfile and Jakarta EE. I won't go into the history of MicroProfile, but both MicroProfile and Jakarta EE are initiatives at the Eclipse Foundation. Both seek to specify server-side Java APIs for building enterprise applications that can have multiple independent implementations, and both initiatives have many of the same participant organizations.
