   Travis is showing two job failures - I restarted one of them as i sense it 
was unrelated, but the other specifically fails one of the new tests added here:
   
   ```text

>             Project: TinkerPop
>          Issue Type: Bug
>          Components: driver
>    Affects Versions: 3.4.8, 3.4.9
>            Reporter: Divij Vaidya
>            Priority: Major
>
> The client does not load balance requests across connections in a threadpool 
> which cause a request failing with timeout even when a connection is 
> available. To verify this, the following test fails:
> {code:java}
> @Test
> public void shouldBalanceConcurrentRequestsAcrossConnections() throws 
> InterruptedException {
>     final int connPoolSize = 16;
>     final Cluster cluster = TestClientFactory.build()
>             .minConnectionPoolSize(connPoolSize)
>             .maxConnectionPoolSize(connPoolSize)
>             .create();
>     final Client.ClusteredClient client = cluster.connect();
>     client.init();
>     try {
>         final RequestMessage.Builder request = 
> client.buildMessage(RequestMessage.build(Tokens.OPS_EVAL))
>                 .add(Tokens.ARGS_GREMLIN, "Thread.sleep(5000)");
>         final Callable<Connection> sendQueryCallable = () -> 
> client.chooseConnection(request.create());
>         final List<Callable<Connection>> listOfTasks = new ArrayList<>();
>         for (int i=0; i<connPoolSize; i++) {
>             listOfTasks.add(sendQueryCallable);
>         }
>         Set<String> channels = new HashSet<>();
>         final List<Future<Connection>> executorSubmitFutures = 
> executorServiceForTesting.invokeAll(listOfTasks);
>         executorSubmitFutures.parallelStream().map(fut -> {
>             try {
>                 return fut.get();
>             } catch (InterruptedException e) {
>                 e.printStackTrace();
>             } catch (ExecutionException e) {
>                 e.printStackTrace();
>             }
>             return null;
>         }).forEach(conn -> channels.add(conn.getChannelId()));
>         
>         System.out.println(channels.size());
>     } finally {
>         cluster.close();
>     }
