Buggy source:
public void validate(Project project){
  URIBuilder requestUri=MMSUtils.getServiceProjectsRefsElementsUri(project);
  if (requestUri == null) {
    return;

Fixed version (ground truth):
public void validate(Project project){
  URIBuilder requestUri=MMSUtils.getServiceProjectsRefsElementsUri(project);
  if (requestUri == null) {
    return;
  }
  for (  String key : images.keySet()) {
    Element e=Converters.getIdToElementConverter().apply(key,project);
    String id=key.replace("String_Node_Str","String_Node_Str");
    requestUri.setPath(requestUri.getPath() + "String_Node_Str" + id);
    JsonNode value;
    String cs="String_Node_Str";
    if ((value=images.get(key).get("String_Node_Str")) != null && value.isTextual()) {
      cs=value.asText();
    }
    requestUri.setParameter("String_Node_Str",cs);
    String extension="String_Node_Str";
    if ((value=images.get(key).get("String_Node_Str")) != null && value.isTextual()) {
      extension=value.asText();
    }
    requestUri.setParameter("String_Node_Str",extension);
    ObjectNode response;
    try {
      HttpRequestBase request=MMSUtils.buildRequest(MMSUtils.HttpRequestType.GET,requestUri);
      request.setHeader("String_Node_Str","String_Node_Str" + extension);
      response=JacksonUtils.parseJsonObject(MMSUtils.sendMMSRequest(project,request));
    }
 catch (    ServerException|IOException|URISyntaxException e1) {
      Application.getInstance().getGUILog().log("String_Node_Str" + e1.getMessage());
      e1.printStackTrace();
      return;
    }
    if (((value=response.get("String_Node_Str")) == null || !value.isTextual() || value.asText().contains("String_Node_Str")) || ((value=response.get("String_Node_Str")) == null || !value.isTextual() || !value.asText().equals(cs))) {

      rule.addViolation(v);
