Dimitar Atanasov Stoikov commented on HHH-5098:
-----------------------------------------------
Hello,
Unfortunately, it is still present in 3.5.2-Final.
It is a blocker for us as well. Please, raise its priority.
We have like this:
==================
@Entity
@Inheritance(JOINED)
public abstract class Atype<A extends Atype<A,C>, C extends Ctype<C,A>>
{
@ManyToOne(targetEntity = Ctype.class)
private C ctype;
}
@Entity
@Inheritance(SINGE_TABLE)
public abstract class Ctype<C extends Ctype<C,A>, A extends Atype<A,C>>
{
@OneToMany(mappedBy = "ctype", targetEntity= Atype.class)
private Set<A> atypeSet;
}
==================
Schema generation works.
Persistence operations work in 3.3.2GA.
Best Regards,
Dimitar

Issue Type: Bug
Components: entity-manager
Affects Versions: 3.5.0-Final, 3.5.1
Reporter: Kahli Burke
Assignee: Gail Badner
Fix For: 3.5.x
Attachments: patch.txt
The following exception is thrown when an entity exists with a collection containing a
parameterized type:
ERROR [AssertionFailure] an assertion failure occured (this may indicate a bug in
Hibernate): org.hibernate.annotations.common.AssertionFailure: Fail to process type
argument in a generic declaration. Type: class

For example if a field exists like:
@OneToMany
List<SomeEntity<SomeClass>> associatedList;
I've attached a patch that includes a test case for the entity-manager project and a
proposed fix.
