> Currently, the {{ConnectionUtils.findAddressUsingStrategy}} method returns the first {{NetworkInterface}} whose address is not a loop back address, not a link local address and an {{Inet4Address}}. Before returning this address, it is retried to connect to the {{JobManager}} using the {{InetAddress.getLocalHost}} address a last time.
> The heuristic, if not choosing the {{InetAddress.getLocalHost}}, often makes no sense because it returns a random {{NetworkInterface}} address. It would be better to simply return the {{InetAddress.getLocalHost()}} instead.
