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.
