Yeah, sorry but it looks I can point that :) I am seeing in 
com.mongodb.MongoClientOptions.Builder that ACKNOWLEDGED is the default 
settings and just verified with debugger that it is really the case. I 
agree that it is bit misleading as WriteConcern.NORMAL is same as 
UNACKNOWLEDGED and "NORMAL" may imply that it's default, but it's not.
