The Jakarta EE 12 release, initially anticipated before the summer of 2026, is now expected to be postponed to the end of the year. This delay follows a one-year lag in the implementation of Jakarta EE 11 by vendors, as they continue to fine-tune the system to meet the required standards. The Jakarta EE Working Group remains committed to aligning their major version releases within six to nine months of Java LTS releases, however, current circumstances have led to the adjustment of the timeline to Q4 2026.
In the meantime, the GlassFish 8.0.0 release marks a significant step forward, providing a solid foundation for the upcoming Jakarta EE 12 support. On another front, Jakarta Persistence 4.0, coupled with Hibernate 8 in its alpha version, is ready for developers to explore and integrate.
The community spirit around Jakarta EE continues to thrive with successful gatherings being a testament to this enthusiasm. Notably, the community-organized JakartaOne meetup in Johannesburg was a resounding success with 136 attendees, effectively filling in for the originally planned larger conference which had to be cancelled.
Looking ahead, the Open Community Experience 2026 invites registrations for those interested in engaging with the ongoing development of Jakarta EE and related technologies. Moreover, the upcoming FOSDEM’26 and Jfokus 2026 conferences will offer further opportunities for developers and enthusiasts to connect, share, and collaborate on the future of Jakarta EE.
