> {{TestApplicationHistoryClientService.testContainers}} and
> {{TestApplicationHistoryClientService.testApplicationAttempts}} both fail
> because the test assertions are assuming a returned Collection is in a
> certain order. The collection comes from a HashMap, so the order is not
> guaranteed, plus, according to [this
> page|http://docs.oracle.com/javase/8/docs/technotes/guides/collections/changes8.html],
> there are situations where the iteration order of a HashMap will be
> different between Java 7 and 8.
> We should fix the test code to not assume a specific ordering.
