Why not 3♣? Because we have a spare Jack? I am not saying that it is a better or a worse bid, but obviously the hand qualifies if it is considered to be non-invitational.
I think 3♣ should show a more distributional hand. 1♠ is the most flexible bid. Over partners 1nt I suppose I can bid 2♣ next, showing a hand that lacks the values for 2♥ and lacks the shape for 3♣...
