Puedo ejecutar el comando desde la terminal. Tengo este programa java simple

 public static void main(String s[]) { new MongoDb(); } public MongoDb() { MongoClient mongoClient = MongoClients.create();//"mongodb://127.0.0.1:27017"); MongoDatabase database = mongoClient.getDatabase("mqtt"); addMqttUser(database); } public void addMqttUser(MongoDatabase database) { MongoCollection<Document> collection = database.getCollection("restaurants"); Document document = new Document("name", "mqtt_user") .append("username", "test22") .append("is_superuser", false) .append("password", "a665a45920422f9d417e4867efdc4fb8a04a1f3fff1fa07e998e86f7f7a27ae3"); collection.insertOne(document, new SingleResultCallback<Void>() { @Override public void onResult(final Void result, final Throwable t) { System.out.println("Inserted!"); } }); }

Estoy recibiendo esto en mi registro
