Sounds good to me, but – to be honest – a simpler solution would be enough for now, at least for me. I actually need something which works on Java 8.
I also want to share an excerpt from an RFC: RFC 1123 2.3 Applications on Multihomed hosts … Application protocol implementations **SHOULD** be prepared to try multiple addresses from the list until success is obtained. … SRC: https://tools.ietf.org/html/rfc1123 Java sadly does not implement this.
