Date Fri, 05 Sep 2008 10:45:44 GMT
SetUniqueList set method use corrupts uniqness
----------------------------------------------

                 Key: COLLECTIONS-304
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-304
             Project: Commons Collections
          Issue Type: Bug
    Affects Versions: 3.2
         Environment: JDK 1.6/Windows/Eclipse Ganymede
            Reporter: Rafał Figas


When set method is used to put element (Strawberry) on list, then it is possible to add the
same element (Strawberry) with add method. Also you cannot add element (Lemon) that has been
once removed with set method. Reproduction code below:


List<String> list = new LinkedList<String>();
SetUniqueList decoratedList = SetUniqueList.decorate(list);

decoratedList.add("Apple");
decoratedList.add("Lemon");
decoratedList.add("Orange");

System.out.println(decoratedList.toString());

decoratedList.set(1, "Strawberry");

System.out.println(decoratedList.toString());

decoratedList.add(1, "Strawberry");

System.out.println(decoratedList.toString());

decoratedList.add(1, "Lemon");

System.out.println(decoratedList.toString());
