The same validation placed on field in @Entity works as expected.

@Entity
public class Customer extends PanacheEntityBase {
  Set<@NotNull @Email String> notificationEmails;
}

Any advice?
Best regards

With Quarkus 3 the javax to jakarta rename happened, check if the Email is still imported from javax

[luca-bassoricci]

Nope, import is correct.
I suppose the problem is related only to config framework because validator is bootstrapped using Validation.buildDefaultValidatorFactory().getValidator(); in io.smallrye.config.validator.BeanValidationConfigValidatorImpl and - maybe - additional configuration is required.

@radcortez wdyt?

[radcortez]

Maybe... we did a change some time ago for config to bootstrap its own Validator. Can you open an issue? Thanks!
