java - matching List in any order when mocking method behavior with Mockito

Question

I have a test using Mockito that has a very strange behavior : it works in debug but fails when running normally. After some investigation, I realized it's because I am mocking methods behavior, passing a list of elements to match. But for some reason, order in the list is not always the same so it doesn't match and what I expect my mock to return is not returned, because the 2 lists are not "equals"

 when(mockStatusCalculatorService.calculateStatus(Arrays.asList(IN_PROGRESS, ABANDONNED,EXPIRED))).thenReturn(ConsolidatedStatus.EXPIRED);

In my case, order of elements to match doesn't matter. So how can I specify this when configuring my mock ?

Adding an answer for newer versions of Mockito and Java 8

when(
   mock.method(argThat(t -> t.containsAll(Arrays.asList(IN_PROGRESS, ABANDONED, EXPIRED))))
).thenReturn(myValue);
