Bulletproof Java Enterprise Applications for The Hard Production Life
summary
Concrete fixes and demos show how to stop synchronous HTTP calls from freezing the JVM: use JAX‑RS timeouts (example 3s timeouts), run services in Docker on Open Liberty with JDK 11/12, and turn blocking endpoints into CompletionStage async handlers so the app doesn’t exhaust the single servlet thread pool. Add MicroProfile Fault Tolerance for bulkhead size 4 queue 4 and circuit breakers configured as window 10, 30% threshold, 3s half‑open. Observability via MicroProfile metrics → Prometheus; orchestration via Kubernetes and service mesh for canaries.
