Buggy source:
protected void evaluateName(String name){
  if (name == null || name.length() == 0 || StringUtils.trimToNull(name) == null) {

    }
  }

Fixed version (ground truth):
protected void evaluateName(String name){
  if (name == null || name.length() == 0 || StringUtils.trimToNull(name) == null) {
    nameStatus=createStatus(IStatus.ERROR,Messages.getString("String_Node_Str"));
  }
 else   if (name.startsWith("String_Node_Str") || name.startsWith("String_Node_Str") || !Pattern.matches(RepositoryConstants.getPattern(getRepositoryObjectType()),name)|| name.trim().contains("String_Node_Str")|| name.trim().contains("String_Node_Str")) {
    nameStatus=createStatus(IStatus.ERROR,Messages.getString("String_Node_Str"));
  }
 else   if (isKeywords(name) || "String_Node_Str".equalsIgnoreCase(name)) {
    nameStatus=createStatus(IStatus.ERROR,Messages.getString("String_Node_Str"));
  }
 else   if (name.equalsIgnoreCase(ProjectManager.getInstance().getCurrentProject().getLabel())) {
    nameStatus=createStatus(IStatus.ERROR,Messages.getString("String_Node_Str"));
  }
 else   if (nameModifiedByUser) {
    if (retrieveNameFinished) {
      if (!isValid(name)) {
        nameStatus=createStatus(IStatus.ERROR,Messages.getString("String_Node_Str"));
      }

        nameStatus=createOkStatus();

    }
 else {
      nameStatus=createStatus(IStatus.ERROR,"String_Node_Str");
    }
  }
