+   * This test catches the problem where the discriminator column is select
+   * but is not skipped if the parent bean is already in the presistence context.
+   * <p>
+   * Test case: We have several trips with different addresses but always the same
+   * driver and car (the cars could be different). So the driver will be loaded
+   * when the first trip is loaded but when the second trip is loaded the driver is
+   * found in the persistence context. So the bean is not read but the index in the
+   * result set is forwarded by the number of properties - however, the vehicle type
+   * column was not being skipped - but the query reads happily - only the data is
+   * then wrong in the address object.
