The distributed development and maintenance paradigmfor component delivery is fraught with problems. One wantsa relationship between developers and clients that is autonomousand anonymous. Yet components written in languagessuch as C++ require the recompilation of all dependentsubsystems when a new version of a component is released.The design of Java's binary format has side-steppedthis constraint, removing the need for total recompilationwith each change. But the potential is not fulfilled if programshave to be stopped to swap in each new component.This paper describes a framework that allows Java programsto be dynamically upgraded. Its key purpose is to allowlibraries that are safe to replace existing libraries withoutadversely affecting running programs. The frameworkprovides developers with a mechanism to release their librariesand provides clients with the surety of only upgradingwhen it is safe to do so.
