Hibernate ORM

Hi,
I am using spring boot 3.2.3 and spring data jpa 3.2.3 .
While making service up getting below error. I have used @Embeddable and @EmbeddedId for composite primary keys. It was working till 2.7.18 spring boot versoin.

Any idea what is causing this error ? Thanks in advance.

This is not a Spring forum and I have no idea what Hibernate ORM version Spring uses. You also didn’t post the entity model that you’re using which causes this. When you include so little information in a question you won’t find any answers.

@Prateek_Pagaria , were you able to resolve this issue with embeddedClass is null ? I am also getting the same error and using spring 3.+ and Hibernate 6.0+.
Here are my embeddable classes.

@Embeddable
@Getter
@Setter
@ToString
@NoArgsConstructor
@AllArgsConstructor
@DynamicUpdate
public class AddressCompositeKey implements Serializable {

    private static final long serialVersionUID = 1234567L;

    @Column(name = "column1_id")
    private UUID column1Id;

    @Column(name = "code")
    private String code;
}

@Entity(name = "address")
@Getter
@Setter
@ToString
@AllArgsConstructor
@NoArgsConstructor
public class Address {

 @EmbeddedId
 private AddressCompositeKey addressCompositeKey;
}
