> I have been getting constant failures of the {{ClientPortBindTest}} unit test
> (see ZOOKEEPER-1256) on my Macbook. I traced the problem to loss of the IPv6
> scope ID on the address chosen for the loopback address in the unit test.
> The address chosen is: fe80:0:0:0:0:0:0:1%1. The scope ID here is 1, after
> the percent sign.
> The scope ID is lost in the {{resolveAndShuffle()}} method of
> {{StaticHostProvider}}. The method uses {{InetAddress.getByAddress()}} which
> apparently does not preserve the scope ID in the host string it is passed.
> {{Inet6Address.getByAddress()}} can, although you have to parse the scope ID
> out of the host string yourself and pass it as its own parameter.
