Driver fails to read `BsonInt64` as Long and results in ClassCastException:
Minimal reproducible example:
https://gist.github.com/aaabramov/89625595893d0ff513d1512b43a21caa
What happens here is that driver reads `field` as an `Integer` and puts it into `org.bson.Document#documentAsMap` then tries to class it as a `Long` in `org.bson.Document#getLong`.
And the interesting thing is we'll try to persist `coll.insertOne(Document("field" -> BsonInt64(Long.MaxValue))).toFuture()` everything would work just fine. So seems that driver chooses resulting type based on its value?
It was working fine with driver `"org.mongodb.scala" %% "mongo-scala-driver" % "2.7.0"`
