Buggy source:
private void createContextsAndSetExecutor(HttpServer server){
  RequestHandler requestHandler=new RequestHandler();
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.setExecutor(new Executor(){
    @Override public void execute(    Runnable command){
      try {
        new Thread(command).start();
      }
 catch (      Exception e) {
        System.err.println("String_Node_Str" + e.getMessage());
        ErrorLogger.log("String_Node_Str","String_Node_Str" + "String_Node_Str" + e.getMessage());
      }
    }
  }
);
}

Fixed version (ground truth):
private void createContextsAndSetExecutor(HttpServer server){
  RequestHandler requestHandler=new RequestHandler();
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);
  server.createContext("String_Node_Str",requestHandler);

  server.setExecutor(new Executor(){
