    Description

      How to repro:
      1. setup /etc/resolv.conf with only ipv6 addresses. In this case we had:

      nameserver 2620:119:5008:1001::106

       
      2. use }}{{dnsSrvEnabled(true) when building the couchbase environment
       
      First the client fails to resolve the dns-srv record:

      2017/08/1811:46:01.163WARN [CouchbaseAsyncCluster] [qtp347978868-17] [sharin20] [wRRvPrP+uZ+udn56nbcg4g==] DNS SRV lookup failed, proceeding with normal bootstrap.
      		 
      java.lang.NumberFormatException: For input string: "119:5008:1001::106"

      then it falls back to non dns-srv behavior which fails:

      2017/08/18 11:46:01.170 INFO [SeedNodesRequest] [qtp347978868-17] [sharin20] [wRRvPrP+uZ+udn56nbcg4g==] Unknown host HDD-2.in-couchbase.ei-ltx1.stg.linkedin.com in bootstrap list. java.net.UnknownHostException: HDD-2.in-couchbase.ei-ltx1.stg.linkedin.com: unknown error
