Hi Mongodb team,

I'm on data analysis in java application and found that for the data(field) type there are some similar definitions,
e.g.
org.bson.types.BSONTimestamp
org.bson.BsonTimestamp

Most of fields' type on java can be matched to classes defined under org.bson.types.* but only bson timestamp is exceptional, which is matched to org.bson.BsonTimestamp.

below is the results of <fieldValue>.getClass().getName(), which is printed by my application.
java.lang.String
org.bson.BsonTimestamp // never be org.bson.types.BSONTimestamp
org.bson.types.ObjectId
org.bson.Document
org.bson.types.MinKey
org.bson.BsonTimestamp
org.bson.types.ObjectId
org.bson.types.MaxKey
java.lang.String
org.bson.Document

it shows that field type comes from both subtype of org.bson.BsonValue and org.bson.types.*

What is the difference between them, or some duplicated definitions?

Can you please give me help or guide?
Thanks.
