Unit test failing with Junit and Hamcrest - Not able to compare data with two List objects

I have the following test that is actually asserting the data within two Lists. But even though the data is same, the test does not pass. I googled and found SO links which pointed to using assertThat(actual, containsInAnyOrder(expected.toArray())); but no luck.

@Test
public void testGetOrderLines() {
    List<OrderLine> expResult = new ArrayList<>();
    OrderLine orderLine = new OrderLine(100, 5, "http://image-url.com", "Baby Gym",
            1, "physical", "http://product-url.com", 100, "pcs", "100-123");
    expResult.add(orderLine);
    List<OrderLine> result = instance.getOrderLines();
    assertThat(expResult, containsInAnyOrder(result.toArray()));
}

Error:
