Support Record as Embeddable

[hantsy]

I tried to use a record as @EmbeddedId id in an entity.

public record RecordEmbeddedId(String id, String id2) {
}

@Entity
public class RecordEmbeddedIdEntity {

    @EmbeddedId
    RecordEmbeddedId id;
    String name;

    // setters and getters
}

When running the testing codes to verify the record support, I got the following errors.

Exception Description: Predeployment of PersistenceUnit [defaultPU] failed.
Internal Exception: Exception [EclipseLink-7246] (Eclipse Persistence Services - 5.0.0-B02.v202404111748): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The Entity class [class com.example.RecordEmbeddedIdEntity] has an embedded attribute [id] of type [class com.example.RecordEmbeddedId] which is NOT an Embeddabl
e class. Probable reason: missing @Embeddable or missing <embeddable> in orm.xml if metadata-complete = true. Please see server.log for more details. [status: CLIENT_ERROR reason: Bad Request]

If I add @Embeddable to record like this.

@Embeddable
public record RecordEmbeddedId(String id, String id2) {
}

Run the tests, it will throw the following exceptions.

Exception [EclipseLink-63] (Eclipse Persistence Services - 5.0.0-B02.v202404111748): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: The instance creation method [com.example.RecordEmbeddedId.<Default Constructor>], with no parameters, does not exist, or is not accessible.
Internal Exception: java.lang.NoSuchMethodException: com.example.RecordEmbeddedId.<init>()
Descriptor: RelationalDescriptor(com.example.RecordEmbeddedId --> [DatabaseTable(RECORDEMBEDDEDIDENTITY)])
