in case of Joined inheritance, my superclass is:

[@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "PERSON_ROLE_TYPE_ID", discriminatorType = DiscriminatorType.INTEGER)
public class PersonRole extends RhEntity {
.
.
.]

And child is:
[@DiscriminatorValue("8")
@PrimaryKeyJoinColumn(name = "USER_ID", foreignKey = @ForeignKey(name = "ARC_FK_PERSON_ROLE_OF_USER"))
public class User extends PersonRole {
.
.
.
]

but when creating schema using hbm2ddl=create, described foreign key name is ignored:

[Hibernate: alter table ARC_USER add constraint FKdeatoofkeuemefs49cnk3tm4p foreign key (USER_ID) references ARC_PERSON_ROLE]

while expected is:

[Hibernate: alter table ARC_USER add constraint ARC_FK_PERSON_ROLE_OF_USER foreign key (USER_ID) references ARC_PERSON_ROLE]
