Jul 1, 2026July 2026 monthly summary for OpenLiberty/open-liberty focusing on delivering targeted improvements, stabilizing behavior, and preparing for ongoing maintainability. What changed: - Internal diagnostics enhancement: Mark MessageUtils as trivial for IBM WebSphere Liberty logging/diagnostics via @Trivial annotation, reducing noise in logs while preserving diagnostic signals. This aligns with IBM RAS practices. - Test expectations aligned with JAX-RS/CXF behavior: Updated test to expect HTTP 500 for CXF Fault exceptions during attachment header limit violations, reflecting actual runtime handling and improving test fidelity. - Code hygiene and copyright refresh: Performed minor code cleanup and updated copyright year to 2026 to maintain compliance and clarity across the codebase. Impact: - Business value: Cleaner diagnostic signals, more accurate failure signaling, and up-to-date legal/ownership metadata support smoother audits and releases. - Technical improvements: Reduced log noise, more reliable test outcomes, and improved maintainability for ongoing Liberty development. Repositories affected: OpenLiberty/open-liberty.

Jun 1, 2026June 2026: Delivered enhancements to CXF integration in Open Liberty focusing on robust attachment handling, security defaults for form parameters, and expanded test coverage. Implemented overlays for CXF AttachmentDeserializer and MessageUtils, added memory thresholds and header/attachment size enforcement, introduced a default maxFormParameterCount of 500, and shipped a CXF-backed runtime security test suite. These changes improve resilience, security posture, and maintainability across CXF runtimes.

Dec 1, 2025Month 2025-12 — OpenLiberty/open-liberty: two feature-focused deliveries strengthening JAX-RS integration and RESTEasy endpoint discovery, complemented by test stabilization efforts. Delivered FAT-based EJB injection tests in JAX-RS with expanded coverage for annotated interfaces and introduced RESTEasy overlay scaffolding with enhanced endpoint discovery. No explicit bug fixes documented; stabilization efforts included re-enabling tests and expanding test coverage. Business value: higher reliability for JAX-RS/EE features, faster release readiness, and improved maintainability through scaffolding and utilities.

Jun 1, 2025June 2025 monthly performance summary for OpenLiberty/open-liberty. Key features delivered: - RESTEasy MP REST Client dynamic classloading and OSGi compatibility: Implemented dynamic classloading to import user bundle classes and load classes from user-provided OSGi bundles; ensured proxies and client interfaces load consistently across Open Liberty environments. Introduced a combined proxy classloader that can see all relevant classes and updated tests to exercise the wrapper path across mpRestClient-3.0/4.0 scenarios. Major bugs fixed: - Packaging and dependency cleanup for REST client modules: cleaned packaging metadata, removed unused entries, updated imports, and addressed FAT errors via server.xml improvements; incorporated code-review refinements to stabilize packaging. - Test stabilization: adjusted tests and ignored a specific SSLHandshakeException in SimpleSSLMultipleServersTest to improve deterministic outcomes. - Code quality updates: copyright date alignment and additional code-review changes. Overall impact and accomplishments: - Significantly improved REST client reliability across OSGi and non-OSGi deployments, enabling smoother customer deployments and proxy usage across module boundaries. - Reduced maintenance risk by cleaning packaging metadata and dependencies, leading to easier future upgrades and fewer FAT-related issues. - Expanded test coverage for dynamic classloading paths and API wrapper usage, increasing confidence in cross-environment compatibility. Technologies/skills demonstrated: - Java modularity, dynamic classloading and OSGi interoperability - RESTEasy MP client integration and environment compatibility - Dependency management and packaging hygiene - Test-driven validation, API wrapper usage

May 1, 2025May 2025 monthly summary for OpenLiberty/open-liberty: Delivered a focused SSL client configuration feature with testing coverage. Implemented SSL Client Configuration Precedence Test (FAT) to ensure explicit keystore/truststore on the JAX-RS ClientBuilder takes precedence over server defaults when a system property is set. Introduced SimpleSSLMultipleServersClientAPITest and a servlet client to validate behavior across multiple servers. Commit d1612e0bda9505bcfb3b4b3fe9e8da5cc2dedd6f documents the FAT addition. No major bugs fixed this month; the work strengthens client-side SSL configuration reliability and reduces deployment risk. Technologies demonstrated include Java, JAX-RS ClientBuilder, SSL/TLS concepts, and FAT-based test automation within OpenLiberty.
