How to Debug Lessons Learnt From 10 Years of #SpringBoot
summary
Ten years of SpringBoot maintenance yields concrete debugging methods and surprises: the repo has 4,395 closed bugs, fixes range from a simple integer overflow in the jar loader to deadlocks solved with thread dumps and flaky localization fixed by forcing English locale. Reproducers as tiny GitHub projects or zip files, full stack traces pasted into IDE stack consoles, writing tests that reproduce regressions, using conditional breakpoints and hit counts, and inspecting bytecode with javap are all shown.
