- **Bean introspection** - The comprehensive `BeanDesc` system provides metadata about JavaBeans, accessed through `BeanDescFactory.getBeanDesc(Class)`
- **Type safety** - Extensive use of generics and null-safe operations throughout the API
- **Resource management** - Proper handling of resources with utilities like `CloseableUtil` and `DisposableUtil`

### Key Architectural Patterns

   * Comparisons between the two should take this into account.

   * <p>Fingerprint2011() is a form of Murmur2 on strings up to 32 bytes and a form of CityHash for
   * longer strings. It could have been one or the other throughout. The main advantage of the
   * combination is that CityHash has a bunch of special cases for short strings that don't need to
   * be replicated here. The result will never be 0 or 1.
