The Poker Meister #-2 - I got pwned!

Is my luck running out with this hand?

Full Tilt Poker $0.25/$0.50 No Limit Hold'em - 7 players - http://www.thehandconverter.com/hands/316071

Hero (CO): $37.00
BTN: $26.45
SB: $48.65
BB: $16.00
UTG: $13.05
UTG+1: $46.35
MP: $20.75

Pre Flop: ($0.75) Hero is CO with Js 9s
UTG raises to $1, 2 folds, Hero calls $1, 3 folds
The only question is whether to raise or smooth. Having no history (0 hands) on UTG, I opt to call.

Flop: ($2.75) 2c 5s 4s (2 players)
UTG checks, Hero bets $1.50, UTG calls $1.50
2 spades? HA! Of course, I'm going to get there!

Turn: ($5.75) Jd (2 players)
UTG checks, Hero bets $3.55, UTG raises to $10.55 all in, Hero calls $7
Probably good enough; If not, I always have the flush draw as well.

River: ($26.85) 8c (2 players - 1 is all in)

Final Pot: $26.85
Hero shows Js 9s (a pair of Jacks)
UTG shows 4h 4c (three of a kind, Fours)
UTG wins $25.55
(Rake: $1.30)
Yuck. The Poker Meister has failed me...
