      Description

      We have a test to validate that this works when connecting to multiple servers in a round-robin fashion but nothing that tests against a single server and it seems that there are some problems around that particular situation. It tends to manifest as:

      Caused by: java.lang.NullPointerException: null
      	at org.apache.tinkerpop.gremlin.driver.ConnectionPool.considerUnavailable(ConnectionPool.java:392) ~[gremlin-driver-3.1.2-SNAPSHOT.jar:3.1.2-SNAPSHOT]

      when the ConnectionPool can not be intialized in any way at start up. If that happens the Client doesn't seem to recover well.
