@Test
void optimisticLockError() {

    // Store the saved entity in two separate entity objects
    ProductEntity entity1 = 
    repository.findById(savedEntity.getId()).get();
    ProductEntity entity2 = 
    repository.findById(savedEntity.getId()).get();

    // Update the entity using the first entity object
    entity1.setName("n1");
    repository.save(entity1);

    //  Update the entity using the second entity object.
    // This should fail since the second entity now holds an old version 
    // number, that is, an Optimistic Lock Error
    assertThrows(OptimisticLockingFailureException.class, () -> {
      entity2.setName("n2");
      repository.save(entity2);
    });

    // Get the updated entity from the database and verify its new state
    ProductEntity updatedEntity = 
    repository.findById(savedEntity.getId()).get();
    assertEquals(1, (int)updatedEntity.getVersion());
    assertEquals("n1", updatedEntity.getName());
}
