JAVA操作Informix 12.10.FC5的nosql出错

在Informix 12.10.FC5版本中，支持Mongo的nosql，需要启动监听如下：java -cp  $INFORMIXDIR/bin/jsonListener.jar com.ibm.nosql.informix.server.ListenerCLI -config  $INFORMIXDIR/etc/jsonListener.properties -start

用java操作：

MongoClient mongoClient = new MongoClient("localhost",27017);

MongoDatabase db = mongoClient.getDatabase("stores_demo");

MongoCollection collection = db.getCollection("customer");

System.out.println(collection.find());//可以正常打印

System.out.println("=========================================");

System.out.println(collection.find().iterator());//出错

错误信息如下：
