Map.merge<http://download.java.net/jdk8/docs/api/java/util/Map.html#merge-K-V-java.util.function.BiFunction->states
that its default implementation is equivalent to:
V oldValue = map.get(key);
V newValue = (oldValue == null) ? value :
remappingFunction.apply(oldValue, value);
if (newValue == null)
map.remove(key);
else if (oldValue == null)
map.remove(key);
else
map.put(key, newValue);
This is not correct as for non-existing or null-value, the non-null newValuw should be added to the map.
