It seems that bytecode enhancement has changed from 5.2 to 5.3:
{code:java}
@Entity
@Cache(usage = CacheConcurrencyStrategy.NONE)
public class Generic extends AbstractGeneric<Generic.Type> {
public enum Type implements Marker {
ONE
}
}
@MappedSuperclass
@Cache(usage = CacheConcurrencyStrategy.NONE)
public class AbstractGeneric<T extends Marker> {
@Id
@GeneratedValue
public int id;
@Access(AccessType.PROPERTY)
private T entity;
private T getEntity() {
return entity;
}
private void setEntity(T entity) {
this.entity = entity;
}
}
public interface Marker {
}
{code}
Using bytecode enhancement and bootstrapping Hibernate results in:

This is because bytecode enhancement creates:
{code:java}
public Generic.Type $$_hibernate_read_entity() {
(...)
}
{code}
In 5.2.17, it looked like
{code:java}
public Marker $$_hibernate_read_entity() {
(...)
{code}
Removing the generic return type from the field and casting to the generic in getEntity() does not work in the test case, but solved the issues in our code stack.
Test case:
