Hi Spark,
When both are null, -1 will be returned. This mocked comparator is used
as a boundary test condition, and under this condition,
if there is null entry contained in tree map, is will not be included in
the SortedMap returned by headMap(null) method.
IMHO you need to be carefull here s

This comparator regards null as the smallest object

if(null == o1) return -1;
if(o1.equals(o2)) {
return 0;

This comparator reg
