Exploring Java OSS with Code Reading
summary
Shows how ChatGPT and Claude plus an IDE debugger and project source speed reading large Java OSS like Spring Boot and Eclipse Collections. Demonstrates step-by-step: ask for module map, generate mermaid sequence diagrams, set breakpoints the assistant recommends, and build a mini-boot (≈300 lines) that reproduces auto-configuration to confirm understanding. Claims this workflow shrinks what took weeks into a few hours and the miniature implementation runs and clarifies real code paths.
