February 2025: Maintenance-focused month for fmeum/bazel with a critical reliability fix in the JacocoInstrumentationProcessor. Addressed a filesystem-specific bug by changing the operation from moving to copying the original .class files, preventing failures during recursive directory traversals that encounter newly created files (e.g., buildbarn remote FUSE workers). This improved build stability and reduced flakiness in instrumentation paths. Impact: Higher CI reliability and smoother build pipelines across diverse filesystem environments; reduced debugging time and faster iteration for instrumentation-related changes. Technologies/skills demonstrated: Java-based instrumentation, robust filesystem handling, patch hygiene with clear commit history, cross-filesystem compatibility, and maintainable code changes in Bazel tooling.
