Tworzę aplikację do przetrzymywania artystów (muzyków i zespołów). Chciałem zrobić tak, że klasy Musician i Band dziedziczą id od klasy Artist zamiast posiadać je osobno. Korzystałem przy tym z tej strony: https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#entity-inheritance. Niestety po przeniesieniu id z klas Musician i Band do Artist aplikacja nie działa poprawnie (Error executing DDL "alter table if exists album_band add constraint FKql5tc77ntd0gqmn5xepkticmr foreign key (album_id) references Artist" via JDBC Statement), i wyrzuca poniższe logi:
