## Summary

Jakarta EE 11 introduces a substantial set of features designed to enhance developer productivity for server-side Java applications. A foundational strength of the ecosystem remains its strict separation between open-source API specifications, hosted by the Eclipse Foundation, and runtime implementations like GlassFish or Open Liberty. This architectural choice eliminates vendor lock-in, enabling organizations to switch application servers with minimal friction. Furthermore, deploying applications via traditional WAR files naturally optimizes Docker image layering by physically separating frequently changing application code from the static framework base artifacts.

Modernizing the stack, version 11 establishes Java 17 as a baseline while fully supporting Java 21, allowing teams to seamlessly leverage Java Records across APIs like Jakarta Validation. A major cross-cutting theme of this release is the consolidation of component models; legacy managed beans have been entirely replaced by Contexts and Dependency Injection (CDI) beans. Additionally, the framework has completely stripped out references to the deprecated Java Security Manager, reflecting a necessary modernization of server-side security paradigms, while preparing to deprecate context injection in Jakarta REST to enforce CDI as the universal standard.

Functionally, developer capabilities are expanded through highly flexible security and robust component injection. The security API now supports multiple authentication mechanisms within a single application, making it possible to concurrently run form authentication for user interfaces and JWT for API endpoints. Authorization is further strengthened by programmatic policies that allow developers to attach dynamic business rules—such as time restrictions or account balances—to standard role-based access checks. Under the hood, the new MethodInvoker API within the CDI framework allows the dependency injection container to automatically supply base objects and parameters for executable methods, significantly reducing boilerplate code and streamlining complex enterprise deployments.
