Hibernate Entity containing elementcollection of embeddables having embeddable crashes in HibernateJpaProvider

[rmschots]

Description

In a spring boot environment, when creating an entity with an elementcollection of embeddables that have an embeddable, I'm getting an error when running the application. I encounter this error when creating a project from the spring boot archetype, and adapting it to spring boot 3.2.4, replacing javax with jakarta, and creating a simple entity structure:

Organization has many OrganizationBankAccount as ElementCollection OrganizationBankAccount has an Embedded SwiftCode SwiftCode contains a single String field

@Entity
@Getter
@Setter
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Organization {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id", nullable = false)
    private UUID id;

    @ElementCollection(fetch = FetchType.EAGER)
    @CollectionTable(name = "organization_bank_account", joinColumns = @JoinColumn(name = "organization_id"))
    @Builder.Default
    @Setter(AccessLevel.PRIVATE)
    private Set<OrganizationBankAccount> bankAccounts = new HashSet<>();
}

@Embeddable
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class OrganizationBankAccount {
    @Embedded
    @AttributeOverride(name = "value", column = @Column(name = "swift_code"))
    private SwiftCode swiftCode;
}

@Getter
@Setter
@Embeddable
@ToString
@EqualsAndHashCode
public class SwiftCode {
    private String value;

    public static SwiftCode of(String swiftCode) {
        return new SwiftCode(swiftCode);
    }

    protected SwiftCode() {
    }

    private SwiftCode(String swiftCode) {
        this.value = swiftCode;
    }
}

Expected behavior

The blaze persistence should allow this kind of structure without crashing

Actual behavior

Steps to reproduce

check out my sample repo and run the application: https://github.com/rmschots/blaze-persistence-demo

Environment

Version: 1.6.11 JPA-Provider: Hibernate 6.4 DBMS: H2 Application Server: Spring boot 3.2.4

FYI: I had the same problem when I was using Spring 3.1 and Hibernate 6.2

Thanks for the report. We'll try to look into this as soon as possible.
