Analysis and Transformation of Idiomatic Crosscutting Concerns in Legacy Software Systems

Abstract

Legacy software systems often suffer from code quality problems. Maintenance of legacy systems can therefore be costly, and the value of legacy systems may diminish due to a lack of adaptability and reliability. Many code quality problems are caused by idiomatic implementation of crosscutting concerns. This work studies the idiomatic implementation of crosscutting concerns in legacy systems, and examines whether modern language technology like aspect-oriented programming can improve the situation.
