Shell Table does not work in Native Compilation

Software:

• Spring Boot: 3.4.0
• Spring Shell: 3.4.0
• GraalVM: graalvm-jdk-23.0.1+11.1
• Java: 21

What I’m doing:

Creating a Spring Shell application and compiling it in native mode. The commands must print a Shell Table with a DTO.

package com.reproducer.shell.model;

import java.util.Objects;

public class SampleDTO {

    private String name;

    private String surname;

    /**
     * @return the name
     */
    public String getName() {
        return this.name;
    }

    /**
     * @param name the name to set
     */
    public void setName(String name) {
        this.name = name;
    }

    /**
     * @return the surname
     */
    public String getSurname() {
        return this.surname;
    }

    /**
     * @param surname the surname to set
     */
    public void setSurname(String surname) {
        this.surname = surname;
    }

    /**
     * @param name
     * @param surname
     */
    public SampleDTO(String name, String surname) {
        this.name = name;
        this.surname = surname;
    }

    /**
     * 
     */
    public SampleDTO() {}

    @Override
    public int hashCode() {
        return Objects.hash(this.name, this.surname);
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (!(obj instanceof SampleDTO other))
            return false;
        return Objects.equals(this.name, other.name) && Objects.equals(this.surname, other.surname);
    }

    @Override
    public String toString() {
        return "SampleDTO [name=" + this.name + ", surname=" + this.surname + "]";
    }
}

Behavior:

• JVM Scenario:

When compiling the Java application into a jar and running it, the framework correctly prints the table.

• Native Scenario:

When compiling the Java application into an executable (I’m using macOS Sonoma Version 14.7.1), running the command to print the Shell Table causes the application to throw an exception.
