----------------------------------------

Talking to Bela yesterday, adding the flag is the quickest solution here and I've narrowed down the use case when to use the flag, so it will be accompanied by plenty of javadoc and I'll blog about it. That said, a solution that doesn't require the flag would be ideal, as Dan suggested, that allows STABLE to cover this situations given the replication timeout value.

> When the HotRodServer starts it inserts its record to __hotRodTopologyCache ({{HotRodServer.addSelfToTopologyView(...)}}).
> However, this put may very easily fail - as the command is broadcasted using NAKACK2 protocol, if the message gets lost and there's no following broadcasted message, the message will be not retransmitted and the put operation times out (Replication timeout), which fails the whole HotRodServer startup, all because of one lost UDP message.
