java - Why don't I get a firewall warning when using minecraft for the first time? -

-

when installed minecraft , started program, didn't firewall warning. minecraft totally written in java. when wrote simple java program myself , used sockets communicating on lan network, got firewall warning. think there way make java program uses network communication without getting firewall warning. dont mean there security leak or something. want same result minecraft. think: when firewall doesn't show me warning/confirmation dialog, there nothing worry about. don't worry safety of minecraft, own program.
