> This problem only happens if you have an Entity with a Generated id that also has the
annotation @Basic(optional = false). If you create a new Entity and then try to persist it
via EntityManager.merge(...) call, you'll get the following stack :
> <openjpa-0.0.0-rnull fatal user error> org.apache.openjpa.persistence.InvalidStateException:
The field "id" of instance "org.apache.openjpa.persistence.jdbc.auto.AutoIncrementEntity@99883308"
contained a null value; the metadata for this field specifies that nulls are illegal.
