  * Complex DI frameworks (Spring Bean*Processors, event listeners, XML config)
  * classpath scanning-based autowiring (See Spring @Component)
  * aspect weaving-based autowiring (See Spring @Configurable)
  * Code littered with annotations that invite aspect-based pointcuts
  * Complex ORMs like hibernate that are incredibly difficult to use properly
