      On Jenkins, we occasionally see this stack trace:

      java.lang.NullPointerException
	at com.mongodb.BaseCluster.getRandomServer(BaseCluster.java:204)
	at com.mongodb.BaseCluster.getServer(BaseCluster.java:75)
	at com.mongodb.DBTCPConnector.getServer(DBTCPConnector.java:650)
	at com.mongodb.DBTCPConnector.access$300(DBTCPConnector.java:39)

	at com.mongodb.DBTCPConnectorTest.testConnectionReservationForReadThenWrite(DBTCPConnectorTest.java:137)

      I've traced it down to ServerAddressSelector.choose returning a list with a single null element in the case where the ServerAddress is no longer in the cluster.
