Abstract

Abstract. Binary component adaptation (BCA) allows components to be adapted and evolved in binary form and on-the-fly (during program loading). BCA rewrites component binaries before (or while) they are loaded, requires no source code access and guarantees release-to-release compatibility. That is, an adaptation is guaranteed to be compatible with a new binary release of the component as long as the new release itself is compatible with clients compiled using the earlier release. We describe our implementation of BCA for Java and demonstrate its usefulness by showing how it can solve a number of important integration and evolution problems. Even though our current implementation was designed for easy integration with Sun’s JDK 1.1 VM rather than for ultimate speed, measurements show that the load-time overhead introduced by BCA is small, in the range of one or two seconds. With its flexibility, relative simple implementation, and low overhead, binary component adaptation could significantly
