Uber engineers migrated over 75,000 test classes from JUnit 4 to JUnit 5 using automated code transformation with OpenRewrite and internal orchestration. By enabling the JUnit Platform for dual execution with Bazel and validating changes through CI, the team modernized testing infrastructure while maintaining correctness at monorepo scale.

Wayne Bell and Dan Gomez Blanco discuss the architectural and cultural shift required to scale observability at Skyscanner. They share how moving to OpenTelemetry decoupled instrumentation from vendors, and explain why treating a platform as a product - with engineers as customers - is the key to reducing incident rates and eliminating technical debt across 800+ microservices.

Discover how the Model Context Protocol (MCP) Java SDK is establishing a new architectural discipline for enterprise LLM integrations. By defining explicit contracts and leveraging MCP servers as anti-corruption layers, it ensures governance, loose coupling, and security alignment with the JVM ecosystem and existing operational practices, moving integrations beyond fragility to resilience.

Microsoft's Russinovich and Hanselman argue in a CACM paper that agentic AI creates an "AI drag" on junior developers while boosting seniors, incentivizing companies to stop hiring entry-level engineers. Entry-level hiring is down 67% since 2022. They propose a preceptor model borrowed from medical education to preserve the talent pipeline.
