A bug about translating Cypher query to Gremlin query


Java code:       
        Client gremlinClient = cluster.connect();
        CypherGremlinClient translatingGremlinClient = CypherGremlinClient.translating(gremlinClient);
        translatingGremlinClient.submit("RETURN [a in [1]|a]");

error message:
        SyntaxException: Empty traversal found in the produced translation! This is likely a bug.
