Some of community members have faced issue
while trying to connect to NoSQL DB Server from SQL Developer V 4.0.3 and beyond. It appears, there's a problem with the version of NoSQL DB client drivers that are shipped with the SQL Developer - the drivers haven't caught up and are erroring while connecting to the NoSQL DB. While, we are working to get that fixed and make it available to our users, here's the suggested workaround
to unblock users.
