March 2025 monthly summary focusing on reliability improvements and feature expansion across two repositories. Key features delivered include: 1) Mockito-based JDBCIOExceptionHandler tests in Apache ActiveMQ replacing JMock with tightened verifications to improve reliability when simulating broker shutdown and to verify that broker.stop is invoked during IO exception handling (commits 54f2e885a7307e7e90db824e3d59f7baae55ce28, 718ce02181d57cfec82de8c7c275501dbdd2cac4). 2) MCP Server for RabbitMQ added in punkpeye/awesome-mcp-servers enabling admin operations and message handling, with README updated (commit deb28482c96d515dbc868a8ad902daa04b10ab51). Major bugs fixed include correcting the test verification for broker.stop to prevent flaky results (commit 718ce02181d57cfec82de8c7c275501dbdd2cac4). Overall impact: reduced flaky test outcomes, improved broker lifecycle reliability during IO errors, and expanded operational tooling for RabbitMQ management. Technologies/skills demonstrated: Mockito-based testing, test reliability engineering, Java testing patterns, MCP server architecture, and documentation updates.
