When there is no internet the service can't start

[Carlosgrr]

When I don't have an active internet connection, specialy when my server is restarting and the internet connection has not yet started, I am getting these errors in all minecraft servers.

I believe that if the internet connection is not availabe the service should start normaly, instead of just printing those errors until an internet connection is found, or another idea would be to expose that option so that I can configure it, but not allowing the service to start until the internet is restored should not be the default behavior.

[itzg]

It's a reasonable request but there are numerous things during startup, even the Minecraft server itself, that assume at least limited network availability.

I'll leave this open for consideration, but it is likely never going to be implemented.
