The problem appears later during a cast where the instance of type DiscriminatedAssociationAttributeMapping is cast to PluralAttributeMapping. https://hibernate.atlassian.net/browse/HHH-18750 Commit: 82a76ac9aa74fadc6c8ddc9f4b4949309ee5eca3 https://github.com/hibernate/hibernate-orm/commit/82a76ac9aa74fadc6c8ddc9...

For your information : @OneToMany with @ManyToOne that uses a @SecondaryTable works perfectly. https://hibernate.atlassian.net/browse/HHH-18750 Compare: https://github.com/hibernate/hibernate-orm/compare/475e780da112...eeaf27e...
