トラブルシューティング

その理由は、インデックスが構築されたときに、ではないとの初めてのことであるstandardGraphFactory.openManagement()オープン・トランザクション、それがこの例外を報告します。単純にコードの後ろに置くmgmt = standardGraphFactory.openManagement();コメントアウトOK。
すなわち：

```java
StandardJanusGraph standardGraphFactory = GraphUtil.getStandardGraphFactory();
        JanusGraphManagement mgmt = standardGraphFactory.openManagement();
        VertexLabel person = mgmt.getVertexLabel("person");
        PropertyKey name = mgmt.getPropertyKey("person_name");
        mgmt.buildIndex("person_name_index", Vertex.class).addKey(name).buildCompositeIndex();
        mgmt.commit();
        GraphTraversalSource g = standardGraphFactory.traversal();
        g.addV("person").property("birthDate", new Date(), "person_name", "limin");
        g.tx().commit();
