Unexpected exception parsing XML document from class path resource in spring boot

Question

I am using spring boot and wrote the following code: package com.luv2code.springdemo;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AnnotationDemoApp {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        Coach theCoach = context.getBean("thatSillyCoach", Coach.class);
        System.out.println(theCoach.getDailyWorkout());
        context.close();
    }

}

Error message:

My project structure:

My applicationContext.xml is outside of com.luv2code.springdemo.

What is the error here?
