hi 各位高手，小弟有个问题请教
我们是java开发环境，在使用 insert （DBO） 方法时 提示这个错误，大家有遇见过吗？
java.lang.AbstractMethodError
at org.bson.BsonBinaryWriter.doWriteObjectId(BsonBinaryWriter.java:245)
at org.bson.AbstractBsonWriter.writeObjectId(AbstractBsonWriter.java:522)

代码如下：
//获取连接
db = sdbDatasource.getConnection();
//获取集合空间
cs = db.getCollectionSpace(spaceName);
//获取集合
cl = cs.getCollection(collectionName);
//更新
// cl.sa.save(toDbObject(record));
BSONObject obj = new BasicBSONObject();
obj.put("name", "James");
obj.put("age", 30);
cl.insert(obj);
