Java News Roundup: JDK 27 in Rampdown, JDK 28 Expert Group, GlassFish, Infinispan, Kotlin

The Java ecosystem is once again moving forward with a steady stream of updates that signal a clear shift toward more maintainable, future‑focused tooling. This week’s roundup highlights JDK 27’s entry into the ramp‑down phase, the creation of a new JDK 28 Expert Group, and a suite of releases that extend support for Jakarta EE, distributed caching, and Kotlin. For teams that rely on Java for mission‑critical workloads, these changes are not just incremental tweaks; they are a roadmap for how the language and its ecosystem will evolve to meet modern demands. For example, the GlassFish Arquillian Connectors Suite now offers a streamlined way to run Jakarta EE TCKs, while Open Liberty’s beta release for June 2026 promises tighter integration with cloud‑native patterns. If your organization has been wrestling with legacy Java stacks, exploring these developments can unlock new efficiencies and reduce technical debt.

The JDK 27 ramp‑down plan is more than a maintenance schedule; it is a signal that the community is ready to retire older, less efficient APIs in favor of a leaner core. By systematically deprecating legacy features, JDK 27 clears the way for JDK 28 to introduce substantive improvements without the baggage of backward compatibility constraints. The formation of the JDK 28 Expert Group, a focused body of seasoned contributors, underscores the intention to drive this transition with precision. Instead of relying on broad community input, the group will channel expertise into targeted enhancements, ensuring that the next release is both robust and forward‑looking. For developers, this means fewer surprises during migration and a clearer path to adopting new language constructs that align with modern cloud‑native practices.

GlassFish’s Arquillian Connectors Suite and the latest maintenance releases for Micronaut and Infinispan further illustrate the ecosystem’s commitment to modularity and interoperability. The connectors simplify Jakarta EE testing, reducing the friction that has historically plagued enterprise developers. Infinispan’s point releases bring performance tweaks and bug fixes that keep distributed caching relevant in a world where data locality and latency are paramount. Micronaut’s updates, meanwhile, reinforce its lightweight, dependency‑injection‑first approach, making it a compelling alternative for microservice architectures that demand rapid startup times and low memory footprints. Together, these releases demonstrate that Java is not merely surviving the shift to cloud‑first development; it is actively shaping it.

Open Liberty’s June 2026 beta release is perhaps the most exciting headline. By embracing a modular, container‑friendly design, Open Liberty allows developers to cherry‑pick the components they need, avoiding the bloat that has historically plagued Java EE. The beta introduces enhanced integration with OpenTelemetry and native image support, positioning it as a bridge between traditional Java and the emerging serverless, event‑driven landscape. For teams looking to modernize their Java applications without abandoning the proven reliability of the language, Open Liberty offers a tangible path forward. It invites developers to experiment with hybrid deployments—combining the robustness of Java with the agility of cloud‑native patterns—without committing to a complete rewrite.

Looking ahead, the convergence of these developments points to a Java ecosystem that is increasingly modular, cloud‑ready, and user‑centric. The JDK 28 Expert Group’s focused roadmap, coupled with the streamlined testing tools from GlassFish and the lightweight runtimes from Micronaut and Open Liberty, suggests that Java is positioning itself as the lingua franca for enterprise applications that must run efficiently across on‑premises, hybrid, and public cloud environments. The question for organizations is no longer whether to adopt Java, but how quickly they can transition from legacy monoliths to these new, more adaptable frameworks. Embracing these updates now will not only future‑proof your stack but also empower your teams to innovate faster and with greater confidence.
