> The following test would throw a ConcurrentModificationException,
> It failed on a SessionFactory with backup properties, but I believe it would fail without the Failover set also:
>    public void testFactory() throws Exception
>    {
>      final ClientSessionFactory factory = createFailoverFactory(); // Just a regular factory with Backup configured
>      
>      for (int i = 0; i < 2; i++)
>      {
>         ClientSession sessions[] = new ClientSession[10];
>         for (int j = 0; j < 10; j++)
>         {
>            sessions[j] = factory.createSession(false, true, true);
>            sessions[j].start();
>         }
>         
>         for (ClientSession session: sessions)
>         {
>            session.close();
>         }
>         
>      }
>
