Jan 1, 2026January 2026 (OpenLiberty/open-liberty): Focused on stabilizing cross-platform test execution and tightening the Maven build to reduce flaky results, with clear business value in CI reliability and release predictability. Key changes include Z/OS testing stability improvements via test-forking adjustments and Maven Surefire updates, a targeted skip of MP40 MicroProfile tests to prevent flaky failures, JAX-RS thread-count robustness adjustments for environments with variable load, and build hygiene updates (copyright headers and a pom.xml typo fix) plus a compatibility-aware revert of Jakarta TCK pom changes.

Dec 1, 2025Month 2025-12 summary for OpenLiberty/open-liberty: Key features delivered include enhancements to the JAX-RS client thread-leak test framework (extending test server classes, new component test configuration, test management annotations, thread leak detection and expiration handling, and logging cleanup) and stability-focused Maven Surefire plugin upgrades (updated versions and fork configuration for improved performance on z/OS). Major bugs fixed include defect 307762 in the thread-leak tests, contributing to more reliable test outcomes. Overall impact: higher confidence in JAX-RS client behavior under leak scenarios, reduced flaky tests, faster CI feedback, and lower maintenance burden. Technologies demonstrated: Java testing patterns, FATServlet, test annotations, thread lifecycle management, and Maven Surefire upgrades, with emphasis on z/OS environments. Business value: improved risk reduction in production deployments due to robust test coverage and more efficient release cycles.

Nov 1, 2025November 2025: OpenLiberty/open-liberty delivered security and stability enhancements with targeted testing coverage. Replaced servlet-4.0 feature with appSecurity-2.0 in server.xml to strengthen security posture. Implemented and backported robust cleanup for CachedOutputStream and delayed resources to reduce leaks under concurrency, with CXF-backed improvements (CXF-9171) across jaxrs-2.0 and jaxrs-2.1. Expanded test coverage by adding a JAX-RS client thread-leak testing suite, including a Fat test to reproduce leak scenarios. These changes reduce operational risk, improve reliability, and elevate security for customers.
