I had this issue too.
As far as I could see, the version field isn't initialized automaticaly. But
once it has a value, it will be automaticaly incremented everytime you
persist the entity.
So what I did was simply initialize the version field to zero during entity
instantiation.
All my entities inherit from BaseEntity, which I declared as folow (It's
annotated for use with JPA):
@MappedSuperclass
public class BaseEntity {
@Id
private Long id;
@NotNull
@Version
private Integer version = 0;
}
