In February 2026, Sanne contributed to the quarkusio/quarkus repository by developing and refining JVM module configuration for development and testing modes. Focusing on backend development and DevOps, Sanne implemented Java module system enhancements to suppress Unsafe warnings in isolated entry points and applied add-opens rules to test classloaders, reducing developer-facing noise. The work included configuring both base and runtime classloaders in development mode and enforcing Java-version checks to prevent unsafe memory access on Java 23 and earlier. By refactoring the JvmModulesReconfigurer into a singleton, Sanne improved efficiency and ensured smoother local development and compatibility across Java versions.
February 2026 — Quarkus: Delivered Development and Testing Mode JVM Module Configuration and Compatibility Improvements for quarkusio/quarkus. Consolidated changes to stabilize JVM module handling in dev/test modes, reduce developer noise, and ensure cross-version compatibility. Key outcomes include suppression of Unsafe warnings in isolated entry points, applying add-opens rules to test classloaders, configuring both base and runtime classloaders in development mode, and enforcing Java-version checks to avoid unsafe memory access settings on Java 23 and earlier. Refactored to reuse the JvmModulesReconfigurer instance via a singleton for efficiency. Business value: smoother local development, fewer runtime warnings, and improved compatibility across Java versions. Technical highlights: Java module system, classloader configuration, and pattern-based refactoring for reuse.
