ConfigurationPropertiesRebinder finally use method.invke(xx) to update field , Is there an issue with memory visibility here ?

@ConfigurationProperties(prefix = "book")
@Component
public class BootConfig {
    private String author;
    private String category;

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    @Override
    public String toString() {
        return "BootConfig{" +
                "author='" + author + '\'' +
                ", category='" + category + '\'' +
                '}';
    }
}

there fields no volatile flag....

Start by locating the ConfigurationPropertiesRebinder implementation and the reflective method invocation referenced in the issue. Review how configuration updates are applied and whether the issue provides enough evidence to establish a memory-visibility bug; done would require a confirmed behavior and a clearly scoped fix or explanation.
