Abstract

In this paper we propose a systematic strategy for migrating crosscutting concerns in existing object-oriented systems to aspect-based solutions. The proposed strategy consists of four steps: mining, exploration, documentation and refactoring of crosscutting concerns. We discuss in detail a new approach to aspect refactoring that is fully integrated with our strategy, and apply the whole strategy to an object-oriented system, namely the JHOTDRAW framework. The result of this migration is made available as an open-source project, which is the largest aspect refactoring available to date. We report on our experiences with conducting this case study and re- flect on the success and challenges of the migration process, as well as on the feasibility of automatic aspect refactoring.
