Nope. MongoDB is very popular in enterprises which are largely dominated by Java i.e. strongly typed. MongoDB actually suits strongly typed languages since you enforce your domain in code rather than in the database.
And since Morphia (https://github.com/mongodb/morphia) is similar to JPA it is trivial to port your existing code to MongoDB. Which then leaves you with the same experience as an SQL database except with a lot of benefits (single binary, easy to query/administer/scale, geo spatial features etc).
I'd not count Java as a sign that people at a place like strongly typed systems: Java is a default. The typing system has so few features, it pales in comparison with the alternatives. Those that are in a JVM and really care about a type system might be using Scala instead.
