diamond-scan: spring/hibernate/weld/quarkus/micronaut O(2^D) hierarchy traversal
5 new defects across 5 repos — all diamond recursion (map/set .put/.add return
value ignored before unconditional recurse):
- spring-0001: AnnotationsScanner.processClassHierarchy TYPE_HIERARCHY mode,
no visited guard, used by every @Transactional/@Autowired/@RequestMapping scan
- hibernate-0001: ClassHierarchyHelper.getImplementedInterfaces, Set.add()
return ignored before unconditional recurse — hibernate-validator
- weld-0004: HierarchyDiscovery.discoverTypes, HashMap.put() return ignored,
CDI bean type closure discovery at startup
- quarkus-0004: HierarchyDiscovery.discoverTypes (ArC, copied from Weld),
same defect — Quarkus startup + native image
- micronaut-0005: NativeElementsHelper.populateTypeHierarchy, no visited guard
- micronaut-0006: GenericUtils.populateTypeArgumentsForInterfaces, recursion
outside containsKey guard
Also rename cpython-0001→0002, 0002→0003, 0003→0004 (pre-existing renumber).
