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

      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:

      The Query:
      <named-native-query name="TestEntityIndexReadonly.findByDueDate"
      SELECT id., cur., tenor.*
      FROM indexes id
      LEFT JOIN types cur ON cur.t_id = id.id_t_cur_id
      LEFT JOIN types tenor ON tenor.t_id = id.id_t_tenor_id

      <!-- ResultSets -->
      <sql-result-set-mapping name="TestEntityIndexReadonly.findByDueDateResult">
      <entity-result entity-class="de.test.openjpa.TestEntityIndexReadonly" />
      <entity-result entity-class="de.test.openjpa.TestEntityCurrencyReadonly" />
      <entity-result entity-class="de.test.openjpa.TestEntityTenorReadonly" />

      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)!

      Hope it helps to find the bug.
