Annotation documentation unclear for getVersion()

The documentation (http://www.hibernate.org/hib_docs/annotations/) mentions getVersion() returns Integer which seems a bit odd to me (I'd expect to return "int") yet it does not discuss this. Is Integer required? Is returning "int" ok? Where can I find out more?

Thanks,

This is just a sample. Hibernate Annotations has nothing specific here compared to Hibernate.

Here is a snipset of the Hibernate reference guide

Code:

 A version or timestamp property should never be null for a detached instance, so Hibernate will detact any instance with a null version or timestamp as transient, no matter what other unsaved-value strategies are specified. Declaring a nullable version or timestamp property is an easy way to avoid any problems with transitive reattachment in Hibernate, especially useful for people using assigned identifiers or composite keys!
