Fix Version: JDO 2 beta
Resolution: Fixed
> Wrong instance returned for Employee-Insurance relationships
> ------------------------------------------------------------
>
> Key: JDO-130
> URL: http://issues.apache.org/jira/browse/JDO-130
> Project: JDO
> Type: Bug
> Components: tck20
> Environment: JPOX
> Reporter: Craig Russell
> Assignee: Erik Bengtson
> Fix For: JDO 2 beta
>
> In the Employee-Insurance relationships, the same table is used for both
> relationships. The thing that distinguishes the relationships is the type of
> the instance. Employee has 0..1 instance of MedicalInsurance and 0..1
> instance of DentalInsurance. Since these are both mapped to the same table,
> the query to retrieve the instance needs to qualify the SQL with the correct
> discriminator depending on the relationship being navigated.
> The incorrect behavior results in a ClassCastException when run with
> application identity:
> test(org.apache.jdo.tck.mapping.CompletenessTest)java.lang.ClassCastException:
