> The resultset of the following native query should has a result of an objectarray with
3 different returnvalues. 
> 1) TestEntityIndexReadonly: the holder entity mapped to table indexes 
> 2) TestEntityCurrencyReadonly: currency mapped to table types 
> 3) TestEntityTenorReadonly: tenor mapped to table types too 
> But i get an Resultset with 3 Objects where the second and the third object are the same
(same instance). 
> 1) TestEntityIndexReadonly: 
> 2) TestEntityCurrencyReadonly: 
> 3) TestEntityCurrencyReadonly: 
> Hint: For the entity-3 i get the same oid as for entity-2. The reason is, the JDBCStoreManager
(Line 1031) "Object oid = base.getObjectId(this, result, null, true, null);" gets the same
oid for entity-2 and entity-3. 
> I will attache the javaclasses and mapping.xml and a screen from the wrong resultset.

> see also: https://issues.apache.org/jira/browse/openjpa-2218. 
> I tried to find out a workaround by removing the abstract parent from TestEntityCurrencyReadonly
and TestEntityTenorReadonly. 
> In this case, i get the correct Objectinstances but the third entity (TestEntityTenorReadonly)
holds the values from TestEntityCurrencyReadonly (also wrong)!
