```
Due to the `Collections.synchronizedNavigableMap`'s java doc:
```
In order to guarantee serial access, it is critical that all access to the
backing navigable map is accomplished through the returned navigable map (or
its views).
It is imperative that the user manually synchronize on the returned
navigable map when traversing any of its collection views, or the collections
views of any of its subMap, headMap or tailMap views, via Iterator, Spliterator
or Stream
```
