Spring Boot: Could not resolve matching constructor when using scope: prototype - spring

Question

Problem
I'm having an issue where, any bean I define with the scope = prototype causes a BeanCreationException:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myClass' defined in class path resource [application-context.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

Example
This is the most basic example I could create that reproduced the problem...
MyClass.java:
Variation 1
public class MyClass {
public String doNothing() {
return "Do nothing";
}
}
Variation 2
public class MyClass {
public MyClass() {}
public String doNothing() {
return "Do nothing";
}
}
application-context.xml
<bean id="myClass"
class="com.example.coaching.models.MyClass"
scope="prototype">
</bean>
MyApp.kt
class MyApp
fun main() {
val context = ClassPathXmlApplicationContext("beanScope-applicationContext.xml")
val myClass = context.getBean("myClass", MyClass::class) as MyClass
println(myClass.doNothing())
}
Other Info
I experienced this in a more complex project, but made this one to try to narrow down the problem and expected I would find something, but I have no clue.
If I change the scope to singleton, it works fine.
Happens with xml configuration as well as annotations
Tried creating MyClass in both Kotlin and Java
Here's my pom.xml just in case
