   ABSTRACT     = {Antipatterns are poor design choices that make 
      object-orien\-ted systems hard to maintain by developers. In this 
      study, we investigate if classes that participate in antipatterns are 
      more change-prone than classes that do not. Specifically, we test the 
      general hypothesis: classes belonging to antipatterns are not more 
      likely than other classes to undergo chan\-ges, to be impacted when 
      fixing issues posted in issue-tracking systems, and in particular to 
      unhandled excep\-tions-related issues---a crucial problem for any 
      software system. We detect 11 antipatterns in 13 releases of Eclipse 
      and study the relations between classes involved in these 
      antipatterns and classes change-, issue-, and unhandled 
      ex\-ception-proneness. We show that, in almost all releases of 
      Eclipse, classes with antipatterns are more change-, issue-, and 
      un\-handled-exception-prone than others. These results justify 
      previous work on the specification and detection of antipatterns and 
      could help focusing quality assurance and testing activities.}
