Buggy source:
public static boolean showContextdialog(IProcess2 process,ContextItem contextItem,IContextManager contextManager,Map<String,Set<String>> addedVarsMap,Set<String> addedVars){
  boolean isAddContext=false;
  ShowAddedContextdialog showDialog=new ShowAddedContextdialog(addedVarsMap,true);
  if (showDialog.open() == Window.OK) {
    List<ContextItem> selectedContextItems=new ArrayList<ContextItem>();
    selectedContextItems.add(contextItem);
    Set<String> groupSet=new HashSet<String>();
    for (    ContextType type : (List<ContextType>)contextItem.getContext()) {
      groupSet.add(type.getName());
    }
    Set<String> curGroupSet=new HashSet<String>();
    for (    IContext context : contextManager.getListContext()) {
      curGroupSet.add(context.getName());
    }
    Set<String> contextGoupNameSet=new HashSet<String>();
    if (!curGroupSet.containsAll(groupSet)) {
      SelectRepositoryContextGroupDialog groupDialog=new SelectRepositoryContextGroupDialog(PlatformUI.getWorkbench().getDisplay().getActiveShell(),contextManager,new ContextManagerHelper(contextManager),selectedContextItems);
      if (Dialog.OK == groupDialog.open()) {
        contextGoupNameSet=groupDialog.getSelectedContextGroupName();
      }
    }
    addContextVarForJob(process,contextItem,contextManager,addedVars,contextGoupNameSet);
    isAddContext=true;
  }
  return isAddContext;
}

Fixed version (ground truth):
public static boolean showContextdialog(IProcess2 process,ContextItem contextItem,IContextManager contextManager,Map<String,Set<String>> addedVarsMap,Set<String> addedVars){
  boolean isAddContext=false;
  ShowAddedContextdialog showDialog=new ShowAddedContextdialog(addedVarsMap,true);
  if (showDialog.open() == Window.OK) {
    if (ConnectionContextHelper.containsVariable(contextManager)) {
      Set<String> addedContext=ConnectionContextHelper.checkAndAddContextVariables(contextItem,addedVars,contextManager,false);
      if (addedContext != null && addedContext.size() > 0) {
        ConnectionContextHelper.addContextVarForJob(process,contextItem,addedVars);
      }
    }
 else {
      List<ContextItem> selectedContextItems=new ArrayList<ContextItem>();
      selectedContextItems.add(contextItem);
      Set<String> groupSet=new HashSet<String>();
      for (      ContextType type : (List<ContextType>)contextItem.getContext()) {
        groupSet.add(type.getName());
      }
      Set<String> curGroupSet=new HashSet<String>();
      for (      IContext context : contextManager.getListContext()) {
        curGroupSet.add(context.getName());
      }
      Set<String> contextGoupNameSet=new HashSet<String>();
      if (!curGroupSet.containsAll(groupSet)) {
        SelectRepositoryContextGroupDialog groupDialog=new SelectRepositoryContextGroupDialog(PlatformUI.getWorkbench().getDisplay().getActiveShell(),contextManager,new ContextManagerHelper(contextManager),selectedContextItems);
        if (Dialog.OK == groupDialog.open()) {
          contextGoupNameSet=groupDialog.getSelectedContextGroupName();
        }
      }
      addContextVarForJob(process,contextItem,contextManager,addedVars,contextGoupNameSet);
    }
    isAddContext=true;
  }
  return isAddContext;
