--------------------------------------
Our TestNG to call the Query.
/**
* Issue:<br/>
* If we join two types with different alliasses, we get for both types
the same instance. <br/>
* This is wrong. We schould get different instances with different
values.<br/>
* This test reproduce this issue and should help to simplify the
behavior.
*
* @throws Exception

> Native-Query with multiple joins to same table returning wrong result

> Key: OPENJPA-2431
> URL: https://issues.apache.org/jira/browse/OPENJPA-2431
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc, jpa, kernel, sql
> Affects Versions: 2.1.0, 2.1.1
> Environment: Websphere 8 Runtime and ApplicationServer
> Windows XP
> J2EE 6
> Oracle 11
> Reporter: axel becker
> Priority: Critical
> Attachments: resultlist.jpeg, TestEntityCurrencyReadonly.java,
> testentityimmutable.jpa.xml, TestEntityIndexReadonly.java,
> TestEntityTenorReadonly.java, TestEntityTypeReadonly.java,
> TestReadonlyPrimaryKey.java
>
>
> 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)!
