May 1, 2026In May 2026, delivered a critical security fix in the apache/activemq-artemis project: fully qualified queue names (FQQN) containing wildcards are now treated as exact matches in security checks, preventing errors where wildcards were ignored. The change includes new tests validating the correct security behavior and preserves strict access control semantics. Key commit: fde82ef9cfe376798a59270a7fcab74b71091d8b (ARTEMIS-6057). Impact includes reduced security risk due to misconfiguration, more reliable authorization decisions, and improved test coverage.

Feb 1, 2026February 2026 (apache/activemq-artemis): Key features delivered include Configuration Management Improvements and Wildcard Delimiter Support in JMX to MOPS Security Matching. Configuration Management Improvements enforce integrity when reloadable configurations are enabled and ensure configuration data is exported without deprecated attributes, improving reliability and admin clarity (commits ARTEMIS-5871, ARTEMIS-5892). Wildcard Delimiter Support adds support for custom wildcard delimiters when converting JMX object names to MOPS security settings, enabling more granular permissions management (commit ARTEMIS-5909). Major bugs fixed: none documented for this period. Overall impact: reduced misconfigurations, clearer configuration exports, and more flexible security policy mapping, contributing to operational stability and scalable access control. Technologies/skills demonstrated: configuration management discipline, JMX-to-MOPS integration, Java-based Artemis codebase, precise commit traceability.

Jun 1, 2025June 2025 performance summary for apache/activemq-artemis: Focused on reliability and stability in configuration handling and data source initialization. Delivered a feature to robustly configure JDBC data sources with correct type conversions, including updating tests to cover default data source class name and string-to-integer conversion via initialSize. Fixed a memory leak in configuration saving by eliminating thread-local BeanUtilsBean usage and instantiating a fresh BeanUtilsBean for each operation. These changes reduce runtime errors, prevent resource leaks, and improve overall system stability in production deployments.
