> Several functions in UnmodifiableMultiValuedMapTest (org.apache.commons.collections4.multimap.UnmodifiableMultiValuedMapTest) assert {{map.toString()}} is equal to a hard-coded string "\{one=[uno, un], two=[dos, deux], three=[tres, trois]}", where the map variable is of type {{MultiValuedMap}}.
> These assertions are flaky because {{map.toString()}} can be equal to any one of the 6 strings where "one=[uno, un]", "two=[dos, deux]" and "three=[tres, trois]" are ordered arbitrarily.
> The functions with this issue are: 
>  * testRemoveException()
>  * testRemoveMappingException()
>  * testClearException
>
