HotRod client's RemoteCacheManager still has a constructor that internally reads hotrod-client.properties (public RemoteCacheManager(boolean start)) and this constructor is not deprecated.

This call leads to parsing "server_list" property by ConfigurationBuilder.addServers(String servers)).

However, IPv6 addresses usually contain colons and so this parsing fails (enable to differentiate the host and port as these are separated by colon too)
