> When a complex graph of nested Embeddable are used in an application data
> model, an issue may surface when the OpenJPA provider tries to instantiate an
> internal state manager that represents the nested Embeddable. This issue
> results in an exception. The Exception being thrown is based on a
> generalized assertion that the nested Embeddable does not have an identity
> associated to it since it is embedded in some entity which bears the identity.
> Sample Exception:
> <openjpa-2.0.2-SNAPSHOT-r422266:1084264 nonfatal user error>
> org.apache.openjpa.persistence.ArgumentException: Cannot manipulate identity
> of type "<embeddable classname>": it's identity type is unknown.
