April 2026 (2026-04) performance summary: Delivered targeted feature improvements across Apache ActiveMQ and ActiveMQ Artemis focused on test compatibility and security hardening. Key outcomes include streamlining IBM JDK test paths to improve compatibility with modern Java runtimes, and hardening management permissions in default broker.xml to enable safe queue/address management by authorized roles while mitigating privilege escalation risks. These changes reduce runtime issues, improve security posture, and provide a clearer foundation for ongoing platform evolution.

In March 2026, delivered key improvements to ActiveMQ's transport test infrastructure to improve reliability and CI throughput. Focused on enabling parallel test execution, reducing cross-test interference, and stabilizing the test suite. Implemented dynamic port allocation for AMQP transport factory tests, ephemeral ports for TcpTransportServerTest to avoid conflicts, and test isolation by disabling JMX in AbstractPendingMessageCursorTest. Added unit tests for transport factory covering mutex stripping and monitor wiring. These changes reduce flaky tests, shorten CI feedback loops, and improve maintainability for future parallel runs. Commits include 014aab2dc4c5e954093146c83fcf98c02249e03e (AMQP: added transport factory unit tests for mutex stripping and monitor wiring. (#1725)) and 07af9d901a0c5b12618c5d8309e671d796f7e275 (AMQ-9365 - use ephemeral port in TcpTransportServerTest and disable JMX in AbstractPendingMessageCursorTest to prevent conflicts in parallel CI runs. (#1819)).
