This paper presents an in-depth study of the adequacy of the AspectJ language for modularizing and reusing exception-handling code. The study consisted of refactoring existing applications so that the code responsible for implementing error-handling strategies was moved to newly created exception handler aspects. We have performed quantitative assessments of five systems—four object-oriented and one aspect-oriented—based on four key quality attributes, namely separation of concerns, coupling, cohe-sion, and conciseness. Our investigation also included a multi-perspective analysis of the refactored systems, including (i) the extent to which error-handling aspects can be reused, (ii) the beneficial and harmful aspectization scenarios for exception handling, and (iii) the scalability of AOP to support the modular-ization of exception handling in the presence of other aspects.
