ABSTRACT
Aspect-oriented programming (AOP) promises to benefit software engineering by providing a layer of abstraction that can modularize system-level concerns. AOP is still a very young area of research and has yet to receive mainstream acceptance in industry. As a result, the industry as a whole lacks experience and knowledge concerning long term maintenance issues with AOP in deployed commercial applications. Fault models that result from software maintenance in aspect-oriented software development (AOSD) are not nearly as well understood as they are for object-oriented software development (OOSD). This paper will explore some of the long-term maintenance issues that can occur with AspectJ, which is an implementation of AOP for the Java programming language. More specifically, the ability of AspectJ (as of version 1.2) to weave into existing bytecode that already contains woven aspects can create unexpected and potentially unsolvable problems. This will hopefully lead to further discussion in the research community that will result in a better understanding of the long-term maintenance issues inherent in AOSD.

Recommendations
Using aspect-orientation to simplify concurrent programming
AOSD '11: Proceedings of the tenth international conference on Aspect-oriented software development companionThe Java programming language offers several basic constructs for concurrent programming. Despite covering everything needed from a functional point of view, the constructs are difficult to use since they require a lot of infrastructural statements ...
Advice weaving in AspectJ
AOSD '04: Proceedings of the 3rd international conference on Aspect-oriented software developmentThis paper describes the implementation of advice weaving in AspectJ. The AspectJ language picks out dynamic join points in a program's execution with pointcuts and uses advice to change the behavior at those join points. The core task of AspectJ's ...
Using AspectJ for component integration in middleware
OOPSLA '03: Companion of the 18th annual ACM SIGPLAN conference on Object-oriented programming, systems, languages, and applicationsThis report discusses experiences applying AspectJ [1] to modularize crosscutting concerns in a middleware product line at IBM®. Aspect oriented programming techniques were used to cleanly separate platform specific facilities for aspects such as error ...
