Centralize Reflections Scanning

Pull Request: Centralize Reflections Scanning

Summary

Replaces 10 scattered new Reflections() calls with a single cached instance via ReflectionsProvider. One classpath scan at boot instead of 10.

---

Changes

1. ReflectionsProvider — cached singleton

Added: di/ReflectionsProvider.java

• Lazy-initialized with double-checked locking (volatile + synchronized)
• Configured with Scanners.TypesAnnotated and Scanners.SubTypes to cover all existing query types
• Exposes getTypesAnnotatedWith(annotation) and getSubTypesOf(type) as static helpers
• clear() method for test teardown

2. Migrated files (10 usages → 0 direct Reflections)

Modified: config/ConfigLoader.java

• new Reflections(Obsidian.getBasePackage()) → ReflectionsProvider.getTypesAnnotatedWith(Config.class)

Modified: database/seeder/SeederLoader.java

• new Reflections(Obsidian.getBasePackage()) → ReflectionsProvider.getTypesAnnotatedWith(Seeder.class)

Modified: database/MigrationManager.java

• new Reflections(basePackage, Scanners.SubTypes) → ReflectionsProvider.getSubTypesOf(Migration.class)

Modified: realtime/websocket/WebSocketLoader.java

• new Reflections(Obsidian.getBasePackage()) → ReflectionsProvider.getTypesAnnotatedWith(WebSocket.class)

Modified: http/controller/ControllerLoader.java

• Two new Reflections() calls replaced (controllers + global advices)

Modified: livecomponents/scanner/LiveComponentScanner.java

• new Reflections(ConfigurationBuilder...) → ReflectionsProvider.getTypesAnnotatedWith(LiveComponentImpl.class)

Modified: di/ComponentScanner.java

• new Reflections(Obsidian.getBasePackage(), Scanners.TypesAnnotated) → ReflectionsProvider.getTypesAnnotatedWith()
• scanAndRegister no longer takes a Reflections parameter

Modified: security/auth/Auth.java

• new org.reflections.Reflections(Obsidian.getBasePackage()) → ReflectionsProvider.getTypesAnnotatedWith(UserDetailsServiceImpl.class)

Modified: security/auth/TokenAuth.java

• new org.reflections.Reflections(Obsidian.getBasePackage()) → ReflectionsProvider.getTypesAnnotatedWith(TokenResolverImpl.class)
