May 2026: Focused on reliability improvements for apache/activemq-artemis, delivering a targeted bug fix in single-connection mode to prevent runaway session creation attempts when the connection factory is in a bad state. The change improves stability for clients using single-connection workflows and reduces resource waste from repeated retries. The work is tracked under ARTEMIS-5987 with a dedicated commit.

April 2026 monthly summary focused on reliability and stability for the Apache ActiveMQ Artemis broker. Delivered a critical startup-path bug fix to eliminate a NullPointerException when starting the broker without Hawtio, and expanded test coverage to guard against regressions in headless deployments. The changes reduce startup incidents, improve uptime for production environments, and reinforce defensive programming practices across the startup sequence.

March 2026: PSI-Polska/wildfly delivered a targeted upgrade of the messaging stack to Artemis 2.52.0 and aligned packaging to improve compatibility and functionality. Key outcomes include upgrading Artemis to 2.52.0 and changing the Maven groupId from org.apache.activemq to org.apache.artemis to reflect Artemis 2.x packaging, and resolving multi-module build conflicts that blocked the upgrade (notably in root pom.xml and module poms). Work is tracked under WFLY-21521 with commit 8abad0c5582e0abeb65af41743304e6870709ef9. This upgrade enhances messaging subsystem stability and compatibility for downstream services, delivering clearer dependency lineage and long-term maintainability. Technologies/skills demonstrated include Artemis 2.52.0 integration, Maven dependency management, multi-module conflict resolution, and issue-tracking alignment.

February 2026 summary for Apache Artemis focused on dependency modernization to bolster stability and performance. Delivered a targeted JCTools library upgrade from 4.0.5 to 4.0.6 to incorporate bug fixes, performance improvements, and potential new features from the dependency update. This change was committed under ARTEMIS-5913 (commit: 6b455f4d05eeec48843ed018f0e74687da8d9d5c) and signed off by Emmanuel Hugonnet, aligning with ongoing maintenance of critical messaging primitives.

March 2025 monthly summary for PSI-Polska/wildfly: Delivered a high-value dependency upgrade and test modernization. Upgraded Apache Artemis to version 2.40.0 and updated tests to account for default-value semantics and new output formatting. Fixed printData test to reflect the output changes, ensuring test suite stability. All work aligns with Jira WFLY-20490 (commit 7f4f3d5eb73b1b283b666b826d55966bfb144961) and supports release readiness.

December 2024 monthly summary for apache/activemq-artemis. Focused security hardening on the large-message path by tightening temporary cache file permissions to prevent unauthorized access. This was implemented in response to a vulnerability identified as ARTEMIS-5172 and committed as 7eaea5a7a6b09b92c5ef0b73a5adaceb8b485ac6.

Monthly performance summary for 2024-11: Focused delivery of a security-related feature in the Apache ActiveMQ Artemis project, with an emphasis on secure handling of temporary large message cache files. The work aligns with risk reduction and reliability goals while maintaining code quality within the repository.

2024-09 Monthly Summary for PSI-Polska/wildfly: Messaging and Security Enhancements through Artemis and commons-codec upgrade. This work upgrades Artemis to 2.37.0 and commons-codec to 1.17.1, improving messaging reliability and security. The change was captured in commit 7bb4b690f9c3067330cdcbbaa64ba53c791048b8 and linked to WFLY-19636 and WFLY-19726. Impact includes better throughput, improved security, and maintained compatibility for deployments.

June 2024 monthly summary for PSI-Polska/wildfly focused on strengthening messaging capabilities and platform stability through the Apache Artemis upgrades. Delivered major feature: upgrade Artemis from 2.34.0 to 2.35.0, with prerequisite upgrade to 2.34.0 and accompanying dependency updates (pem-kesytore 2.4.0, commons-io 2.16.1). This work required careful dependency alignment and validation, tied to Jira issues WFLY-19166 and WFLY-19437. No separate bug fixes were recorded in this period; however, the upgrade delivers improved messaging performance, throughput, and reliability for WildFly-based deployments. Technologies demonstrated include Java, Apache Artemis, WildFly, and Maven/Gradle-style dependency management. Impact: reduced messaging latency, better scalability, easier future maintenance due to aligned dependencies.

In February 2024, delivered stability and compatibility improvements for PSI-Polska/wildfly by upgrading Apache Artemis to 2.32.0, addressing core dependency issues, and implementing inclusive terminology updates across the platform. A targeted fix to Artemis-core-client by excluding bouncycastle resolved Elytron test-suite failures, resulting in a more reliable build and test cycle. All work is tracked under WFLY-18982 with clear commits for auditability.
