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.
