Read on infoq.com

Summary

InfoQ’s Java roundup lists the GA release of JDK 27, early‑access build 16 of JDK 28, BellSoft’s Liberica JDK 27, Jakarta EE 12 updates, Open J Proxy 1.0 (with JDBC cache and HikariCP leak detection), A2A Jakarta 1.0, Azul Payara 7.4.0 (MicroProfile 7.1, OpenTelemetry migration), JHipster 9.4 (Playwright, esbuild), Ktor 3.6 (OIDC auto‑discovery), BoxLang 1.17 (module service, syntax checker) and…

  • JDK 27 ships with nine JEPs; JDK 28 early‑access build 16 adds bug fixes.
  • Open J Proxy 1.0 adds a local cache for DatabaseMetaData/ResultSetMetaData and a HikariCP leak‑detection property.
  • Azul Payara 7.4 drops MicroProfile OpenTracing in favor of OpenTelemetry @WithSpan.
  • JHipster 9.4 switches Angular micro‑frontend builds from Webpack Module Federation to esbuild + Native Federation.

The announcements surface incremental but practical improvements that affect day‑to‑day Java development: newer JDK releases, tighter JDBC tooling, migration paths for observability annotations, and lighter‑weight build/CLI options that can reduce friction in modern cloud‑native Java stacks.

    Typed Domain Grounding (TDG) embeds a DSL inside a mainstream language the LLM already knows (e.g., Kotlin) and uses the host compiler as an oracle. The author describes five building blocks—embedding, choosing a host language with high training‑data frequency, compiler‑driven type safety, a generate‑compile‑repair loop, and an on‑demand teaching tool—and shows measured results from kUML, a Kotli…

  6. App Intents: One Java Declaration for Siri, Spotlight, and Shortcuts

    Codename One adds @AppIntent annotations that let a static Java method be exposed as a Siri, Spotlight, or Android shortcut. The build‑time processor generates native declarations, a reflection‑free dispatch table, and validates the intent metadata. Handlers can be headless, accept typed parameters, return results, and be invoked internally via Intents.invoke(). Entities enable system‑driven disa…
