Buggy source:
private Response saveTopicByIdOrName(String topicNameOrId,String requestContent,String httpMethod){
  Topic topicToBeSaved=astroboaClient.getImportService().importTopic(requestContent,false);
  boolean entityIsNew=false;
  if (CmsConstants.UUIDPattern.matcher(topicNameOrId).matches()) {
    if (topicToBeSaved.getId() == null) {
      topicToBeSaved.setId(topicNameOrId);
      entityIsNew=true;
    }
 else {
      if (!StringUtils.equals(topicNameOrId,topicToBeSaved.getId())) {
        logger.warn("String_Node_Str" + httpMethod + "String_Node_Str"+ topicNameOrId+ "String_Node_Str"+ topicToBeSaved.getId());
        throw new WebApplicationException(HttpURLConnection.HTTP_BAD_REQUEST);
      }
    }
  }
 else {
    Topic existedTopic=null;
    TopicCriteria topicCriteria=CmsCriteriaFactory.newTopicCriteria();
    topicCriteria.addNameEqualsCriterion(topicNameOrId);
    topicCriteria.setOffsetAndLimit(0,1);
    CmsOutcome<Topic> cmsOutcome=astroboaClient.getTopicService().searchTopics(topicCriteria,ResourceRepresentationType.TOPIC_LIST);
    if (cmsOutcome.getCount() >= 1) {
      existedTopic=(Topic)cmsOutcome.getResults().get(0);
    }
 else {
      entityIsNew=true;
    }
    if (topicToBeSaved.getId() == null) {
      if (existedTopic != null) {
        topicToBeSaved.setId(existedTopic.getId());
      }
    }

Fixed version (ground truth):
private Response saveTopicByIdOrName(String topicNameOrId,String requestContent,String httpMethod){
  Topic topicToBeSaved=astroboaClient.getImportService().importTopic(requestContent,false);
  Topic existingTopic=astroboaClient.getTopicService().getTopic(topicNameOrId,ResourceRepresentationType.TOPIC_INSTANCE,FetchLevel.ENTITY,false);
  boolean entityIsNew=existingTopic == null;
  if (CmsConstants.UUIDPattern.matcher(topicNameOrId).matches()) {
    if (topicToBeSaved.getId() == null) {
      topicToBeSaved.setId(topicNameOrId);
    }
 else {
      if (!StringUtils.equals(topicNameOrId,topicToBeSaved.getId())) {
        logger.warn("String_Node_Str" + httpMethod + "String_Node_Str"+ topicNameOrId+ "String_Node_Str"+ topicToBeSaved.getId());
        throw new WebApplicationException(HttpURLConnection.HTTP_BAD_REQUEST);
      }
    }
  }
 else {
    if (topicToBeSaved.getId() == null) {
      if (existingTopic != null) {
        topicToBeSaved.setId(existingTopic.getId());
      }
    }
 else {
      if (existingTopic != null) {
        if (!StringUtils.equals(existingTopic.getId(),topicToBeSaved.getId())) {
          logger.warn("String_Node_Str" + httpMethod + "String_Node_Str"+ topicNameOrId+ "String_Node_Str"+ existingTopic.getId()+ "String_Node_Str"+ topicToBeSaved.getId());
          throw new WebApplicationException(HttpURLConnection.HTTP_BAD_REQUEST);
        }
      }
    }

  return saveTopic(topicToBeSaved,httpMethod,requestContent,entityIsNew);
