> Consider the following scenario. Note that the referencedColumnName in Dependent5a.java
does not exist in the target table. Currently OpenJPA throws PersistenceException. The correct
exception should be ArgumentException indicating that         "org.apache.openjpa.persistence.enhance.identity.Dependent5a.emp"
defines a target of "xFIRSTNAME" for column "FIRSTNAME", but that target does not exist in
table "Employee5".
> @Entity
> @IdClass(DependentId5.class)
> public class Dependent5a implements Serializable {
>     private static final long serialVersionUID = 1L;
>     @Id
>     String name;
>     
>     @Id
>     @JoinColumns({
>        @JoinColumn(name="FIRSTNAME", referencedColumnName="xFIRSTNAME"),
>        @JoinColumn(name="LASTNAME", referencedColumnName="yLASTNAME")
>     })
>     @ManyToOne
>     Employee5 emp;
> ...
> }
> @Entity
> public class Employee5 implements Serializable {
>     private static final long serialVersionUID = 1L;
>     @EmbeddedId 
>     EmployeeId5 empId;
> ...
> }
> @Embeddable
> public class EmployeeId5 implements java.io.Serializable {
>     String firstName;
>     String lastName;
> ...
> }
