Buggy source:
public String[] getActionExpressions(Action action,StructureSource source){
  if (ActionType.URL_REDIRECT_LITERAL.equals(action.getType())) {
    URLValue uv=(URLValue)action.getValue();

      List expList=new ArrayList();

        exp=handle.getURI();
        if (!expList.contains(exp)) {
          expList.add(exp);
        }
      }
 else       if (DesignChoiceConstants.ACTION_LINK_TYPE_BOOKMARK_LINK.equals(handle.getLinkType())) {
        exp=handle.getTargetBookmark();
        if (!expList.contains(exp)) {
          expList.add(exp);
        }

Fixed version (ground truth):

      List expList=new ArrayList();
      String exp;
      if (DesignChoiceConstants.ACTION_LINK_TYPE_HYPERLINK.equals(handle.getLinkType())) {
        exp=handle.getURI();
        if (!expList.contains(exp)) {
          expList.add(exp);
        }
      }
 else       if (DesignChoiceConstants.ACTION_LINK_TYPE_BOOKMARK_LINK.equals(handle.getLinkType())) {
        exp=handle.getTargetBookmark();
        if (!expList.contains(exp)) {
          expList.add(exp);
        }
      }
 else       if (DesignChoiceConstants.ACTION_LINK_TYPE_DRILL_THROUGH.equals(handle.getLinkType())) {
