Describe the bug

I store an object with this inside:

private final ConcurrentSkipListMap<InstantRange, Lazy<List<AuditEvent>>> eventsByPeriod = new ConcurrentSkipListMap<>(new Range.Comparator<>());

But the comparator in the constructor is not stored, so it remains NULL upon loading the map. This causes nasty run-time errors (in my case weeks after deployment!), because without the backing comparator, the key is expected to be Comparable:

 java.lang.ClassCastException: class com.utilities.InstantRange cannot be cast to class java.lang.Comparable
