Issue with unique index - Mongodb

[regis-leray]

Im using nosqlunit-mongodb-0.7.7, mongodb java driver 2.10.1, with remote mongodb-10gen 2.4.6 con ubuntu

And when im usign this sample

{
"user": {
    "indexes": [
            {
                "index": {"code": 1},
                "options": {"unique" : "true"}
            }
    ],
    "data":[
            {"id":1,"code":"JSON dataset"},
            {"id":2,"code":"Another row"}
    ]
   }
}

Here my unit test

  @Rule
    public MongoDbRule remoteMongoDbRule = new MongoDbRule(mongoDb()
            .databaseName("portfolio_test")
            .host("localhost")
            .port(27017)
            .username("portfolio")
            .password("portfolio")
            .build());

    @Test
    @UsingDataSet(locations = "UserDocument.json", loadStrategy = LoadStrategyEnum.CLEAN_INSERT)
    public void shouldNotCreateDuplicateCodeUser() {

     }

Im getting this stacktrace

java.lang.IllegalArgumentException: Unexpected error reading data set file.

PS: if im removing the "unique" options no error.

[regis-leray]

I changed the code based on the mongo db java documentation

com.lordofthejars.nosqlunit.mongodb.DefaultInsertionStrategy.insertIndexes(DefaultInsertionStrategy.java:84)

if(index.containsField(INDEX_OPTIONS)) {
                DBObject indexOptions = (DBObject)index.get(INDEX_OPTIONS);
                indexedCollection.ensureIndex(indexKeys, indexOptions);
            } else {
                indexedCollection.ensureIndex(indexKeys);
            }

http://docs.mongodb.org/manual/tutorial/create-a-unique-index/

And everything is working.

PS we should use ensureIndex fro the default index creation, Based on the documentation and the feeback i read on stackoverflow.
