Notes
- Abstract classes is evil
- Enums is evilEnums should be avoided because not extensibles. Use Strings and constants.
- Expose as less as possible dependencies on third-party libraries, especially like hibernate and even such as commons-collections
- Provide all the required classes to correctly and simply write unit tests. For example if interface implementations must not exposed in public API, then they can be available in a public package named "internal".

Good patterns
Examples: Sensor/SensorContext, Decorator/DecoratorContext
Code Block interface Executor { void execute(Context context); }
