- **Adapter Pattern** - Logging adapters (`JclLoggerAdapter`, `JulLoggerAdapter`) for different logging frameworks
- **Template Method** - Resource traversal utilities with customizable handlers
- **Utility Classes** - All core functionality exposed through static utility methods for easy access

### Performance Optimizations
- **Caching** - Bean descriptors and reflection metadata are cached for improved performance
