Looks basic and simple: A have a JSON string and I want to store it in MongoDB as JSON document.
In java driver 2.xx I could use com.mongodb.util.JSON.parse(String jsonString)
to get DBObject and then store it in collection.
In driver 3.0 JSON.parse still gives DBObject, but rest of API uses org.bson.Document class which looks as incompatible with DBObject.
How to do it in driver version 3.0?
