Follows <a href="https://tsvinc.dev/posts/quarkus-two-stacked-bottlenecks/">Part 20</a>, where two stacked bottlenecks throttled Quarkus. Assumes familiarity with declarative HTTP clients and retry semantics.</em></p> <p>Porting 10 HTTP clients from Micronaut to Quarkus and Spring Boot produced two retry bugs. One framework over-retried by ~50%. The other silently never retried HTTP 5xx at all. Both ports passed every functional test. Both shipped code comments claiming parity with the original.</p> <p>The bugs were mirror images, caused by completely different mechanisms, and invisible without a benchmark that injects failures and counts upstream calls.</p>
