In this paper, we expose the “last line effect,” the phenomenon that the last line or statement in a micro-clone is much more likely to contain an error than the previous lines or statements. We do this by analyzing 208 open source projects...

Managing clones using dynamic change tracking and resolution: Helping developers to cope with changing clone fragments

By many, code cloning is nowadays recognized as a threat to the maintainability of source code. Many clone detection strategies have been proposed and a considerable number of removal strategies, mostly based on refactoring techniques, has been shown. However, recent research has showed that clones can often not be removed easily and other...
