Concurrent systems tend to have certain properties that are not localized in single modular units, but their implementations cut across functional components, increasing coupling and making modular units difficult to reuse and adapt. Example properties include concurrency, synchronization, and authentication. This problem is particularly apparent in systems with evolving requirements, as adapting code that is not localized in single modular units proves to be a tedious process. In this paper we discuss issues related to requirements of concurrent software systems to provide explicit support for these cross‐cutting concerns, and we present the Aspect Moderator, a framework extension to the object model that can ease the development of concurrent object‐oriented systems.
