Jan 1, 2026January 2026 monthly performance summary for OpenLiberty/open-liberty. Delivered key feature enabling asynchronous HTTP client connections and concurrency enhancements, including an AsyncClientConnectionServlet to support concurrent requests for the calculator web service. Implemented tests, configuration updates, and new stubs/WSDL to enable async operations. No major bugs fixed this month; focus remained on reliability and performance improvements. Overall impact includes increased scalability and throughput for HTTP client interactions, better resilience under parallel workloads, and readiness for async integration patterns. Technologies demonstrated include Java async programming, CXF integration, HTTP configuration, test-driven development, WSDL/stub generation, and deployment/configuration changes. Business value: improved responsiveness and higher concurrent request handling, enabling faster end-user experiences and smoother integration with async client workflows.

Oct 1, 2025OpenLiberty/open-liberty — October 2025: Delivered two major features and a critical bug fix that collectively improve reliability, developer experience, and business value. Feature delivery includes (1) Attachment handling improvements with refactored logic, new attachment action enum, and streamlined property retrieval to improve message processing reliability, and (2) Open Liberty CI pipeline and standards checks introducing delivery standards compliance, external contributor notifications, and personal build processes to raise code quality and contributor experience. Bug fix: Disabled MTOM for JAX-WS responses to resolve interoperability issues and improve performance when handling binary payloads. Impact: more robust attachment processing, faster CI feedback and onboarding for contributors, reduced support overhead, and increased stability for customers. Technologies demonstrated: Java, Open Liberty framework, JAX-WS MTOM handling, CI/CD automation, Git workflows, code refactoring, and enum usage.

Jun 1, 2025June 2025 monthly summary for OpenLiberty/open-liberty: Delivered a Performance Monitoring Interceptor Refactor for Apache CXF, introducing a base interceptor to handle message response times and consolidating logic by removing the previous outgoing-specific interceptor. Fixed a IllegalArgumentException related to special characters in WSDL/service/operation names by adding a skipCounter and expanding validation tests; included SpecialCharacterSkipTestDispatch and broader @WebServiceRef/endpoints configurations. Expanded test coverage and robustness for edge cases with new tests and configurations. Overall impact includes improved observability, reliability, and maintainability of the web service stack, reduced risk of runtime errors in CXF integrations, and stronger validation for character handling in service definitions.
