   ABSTRACT     = {Code smells are poor implementation choices, thought to 
      make object-orien\-ted systems hard to maintain. In this study, we 
      investigate if classes with code smells are more change-prone than 
      classes without smells. Specifically, we test the general hypothesis: 
      classes with code smells are not more change prone than other 
      classes. We detect 29 code smells in 9 releases of Azureus and in 13 
      releases of Eclipse, and study the relation between classes with 
      these code smells and class change-proneness. We show that, in almost 
      all releases of Azureus and Eclipse, classes with code smells are 
      more change-prone than others, and that specific smells are more 
      correlated than others to change-proneness. These results justify 
      \emph{a posteriori} previous work on the specification and detection 
      of code smells and could help focusing quality assurance and testing 
      activities.}
