Spring BeanWrapperImpl NPE in setWrappedInstance after invoking getPropertyValue

• Java 17
• Spring boot 3.0.0

I was trying to invoke setWrappedInstance to set a new object on BeanWrapperImpl, but I got NullPointerException after invoking getPropertyValue.

Below is how I reproduce this issue: LightSaber, Person, Jedi define:

public interface LightSaber {
    void getLightSaber();
}

import lombok.Data;

@Data
public class Person implements LightSaber {
    private String firstName;
    private String lastName;

    @Override
    public void getLightSaber() {
        System.out.println("get light saber");
    }
}

import lombok.Data;

@Data
public class Jedi extends Person {
}

My test code:

    @Test
    void setBeanWrapperInstance_mockSetInstanceTwice() {
        BeanWrapperImpl beanWrapper = new BeanWrapperImpl(Jedi.class);

        LightSaber luke = new Jedi(){{setFirstName("Luke"); setLastName("Skywalker");}};
        beanWrapper.setWrappedInstance(luke);
        Assertions.assertEquals("Luke", beanWrapper.getPropertyValue("firstName"));

        LightSaber anakin = new Jedi(){{setFirstName("Anakin"); setLastName("Skywalker");}};
        beanWrapper.setWrappedInstance(anakin);

        Assertions.assertEquals("Anakin", beanWrapper.getPropertyValue("firstName"));
    }

Error Output:

java.lang.NullPointerException: Cannot invoke "java.beans.BeanDescriptor.getBeanClass()" because the return value of "java.beans.BeanInfo.getBeanDescriptor()" is null
