siren-join java api出错

   使用siren-join 2.2.0-1 ，这样访问无问题
curl -XGET 'http://172.22.1.104:9200/sp_gf/_coordinate_search?pretty' -d '{ "query" : {"filtered" : {"query" : {"match_all" : { }},"filter" : {"filterjoin" : {"s_1_yb" : {"indices" : ["sp_c"],"path" : "s_1_yb","query" : { "term" : {"s_1_yb" : "512099"}}}}}}}}'
    
    用java api访问就会出错，代码如下：
                SearchResponse sr = new CoordinateSearchRequestBuilder(client).setIndices("sp_gf").setQuery(                QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery()

                        ,solutions.siren.join.index.query.QueryBuilders.filterJoin("s_1_yb").indices("sp_c").path("s_1_yb").query(                                QueryBuilders.termQuery("s_1_yb", "512099")))).setSize(1000).execute().actionGet();
    There is the exception:
    java.lang.NullPointerException
