Export do not correctly serialize Mongo date

When serializing a Mongo Document with date, it serializes it in the following format:

{ "$date" : 1532111665089 }

Which is not following the STRICT rules of a JSON file: https://jira.mongodb.org/browse/JAVA-1772
Need to update to Java Mongo 3.5 in order to be able to change the way the computation is done.
