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 ``` ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
