Hotswapping library

HotSwap provides a robust library for updating the implementation of an object at runtime (aka hotswapping). This is achieved through recompilation, dynamic class reloading, and object state migration throughout the life of an application. Hotswapping makes Java feel more like an interpreted language than a compiled language; it is fundamentally useful for runtime development of an application (application evolution or incremental development).
