Now we don't provide support for some built-in components mentioned in JSR-299 3.6:

3.6. Additional built-in beans

A Java EE or embeddable EJB container must provide the following built-in beans, all of which have qualifier @Default:

• a bean with bean type javax.transaction.UserTransaction, allowing injection of a reference to the JTA User-
  Transaction,
• a bean with bean type javax.security.Principal, allowing injection of a Principal representing the current caller
  identity,
• a bean with bean type javax.validation.ValidationFactory, allowing injection of the default Bean Validation Val-
  idationFactory, and
• a bean with bean type javax.validation.Validator, allowing injection of a Validator for the default Bean Valida-
  tion ValidationFactory.

These beans are passivation capable dependencies, as defined in Section 6.6.2, "Passivation capable dependencies".
