micronaut-0004: AbstractAnnotationMetadataBuilder.processAnnotation O(2^D) diamond recursion in meta-annotation stereotype traversal. isProcessed() guard tracks only current-path ancestors, not globally visited nodes — diamond meta-annotation hierarchies cause exponential re-visits of shared base annotations (e.g. @Transactional + @Retryable both extend @InterceptorBinding). 13x at D=8, 41x at D=10. 10/10 unit tests PASS. quarkus-0003 unit tests: added to QuarkusTest.java for the existing quarkus-0003 BeanDeployment.recursiveBuild diamond defect. 9/9 PASS. CLEAN markers: camel, hazelcast, tomcat, undertow, vertx — no diamond recursion pattern found. Hazelcast uses proper Tarjan algorithm. Tomcat uses iterative constraint propagation.

# Vert.x — Diamond Recursion (CWE-407 O(2^D)) Scan: CLEAN
|
|
|
|
**Pattern:** Recursive cycle-detection / dependency traversal without a visited set
|
|
(exponential re-visitation on diamond-shaped DAGs)
|
|
**Scan date:** 2026-03-29
|
|
**Scope:** `vertx-core/src/main/java/io/vertx/`
|
|
|
|
## Methods Checked
|
|
|
|
| Method | Location | Guard | Result |
|
|
|--------|----------|-------|--------|
|
|
| Module/verticle dependency ordering | `vertx-core/src/main/java/` | No recursive dependency graph traversal found | CLEAN |
|
|
| HA manager (beyond vertx-0001) | `HAManager.java` | vertx-0001 already patched list-scan; no recursive graph traversal | CLEAN |
|
|
|
|
## Conclusion
|
|
|
|
Vert.x does not implement a plugin/module dependency graph with recursive traversal.
|
|
No diamond-recursion pattern was found beyond the previously identified vertx-0001.
