Quarkus has `@Timeout`, `@Retry`, and `@Fallback`. A mocked exception skips the HTTP client, so it does not prove those annotations. Goblin injects latency and HTTP failures at the JAX-RS boundary. I targeted one inventory resource, left the public quote endpoint reachable, and showed the caller returning fallback data. The 0.0.1 engine stays inactive in the packaged app. https://www.the-main-thread.com/p/quarkus-goblin-chaos-engineering #Quarkus #Java #ChaosEngineering #FaultTolerance
