Jakarta EE 11 marks a pivotal moment in enterprise Java development with its official release, accomplished despite delays due to comprehensive refactoring of the Technology Compatibility Kit (TCK). This significant release introduces one new specification, Jakarta Data 1.0, alongside 16 updated specifications. The modernization efforts included transitioning the TCK from Ant to Maven and replacing TestHarness with Arquillian, successfully addressing technical debt and enhancing compatibility testing.
Jakarta EE 11 is defined by its three profiles: Platform, Web Profile, and the Core Profile, the latter of which specifically caters to microservices and cloud-native applications. A noteworthy aspect of this release is the broad inclusion of new features such as Java Records support, Virtual Threads integration, and the introduction of the CDI Lite specification. Additionally, deprecated elements like SecurityManager references have been removed to streamline the framework.
The Eclipse GlassFish project played a crucial role in ratifying the Platform and Web Profile specifications, achieving a landmark status as the first implementation to pass both TCKs. Eclipse GlassFish updates further include support for JDK 24, a 20% improvement in deployment performance, critical security fixes, and the initiation of experimental virtual thread support. The enhancements in connection pool management and the admin login process make GlassFish a more modern, secure, and high-performance server suitable for a wide range of enterprise Java applications.
Meanwhile, WildFly and Open Liberty have contributed by ratifying the Core Profile, emphasizing their role in supporting microservices. Red Hat’s introduction of the Agent2Agent Java SDK, improvements in WildFly, and recent updates in other frameworks like Spring Cloud, GraphQL, and JobRunr, illustrate the vibrant ecosystem that continues to evolve around Jakarta EE.
Jakarta EE 11 affirms its commitment to driving forward enterprise Java development, offering robust frameworks and tools to empower developers to build efficient, future-proof applications.
