> {{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.
