Wildlfy logs a warning "WFLYEJB0463: Invalid transaction attribute type REQUIRED on SFSB lifecycle method Method postConstruct() of class class com.test.Test, valid types are REQUIRES_NEW and NOT_SUPPORTED. Method will be treated as NOT_SUPPORTED." for @Stateful-components with CDI lifecycle annotations, even if the Class does not define any Transaction-Attributes:
The warning is only created when the @PostConstruct-method is on the class itself and not inherited (which does not make any difference). If the class extends another class, which declares a @PostConstruct-method, the warning does not appear.
