JJ near bubble - badly misplayed?

[Isura]

Not pushing preflop seems really wrong now. And I'm not too fond of pushing the flop into 2 bigger stacks. How bad is this hand?

Party Poker No-Limit Hold'em Tourney, Big Blind is t200 (7 handed) converter

UTG (t305)
MP1 (t535)
MP2 (t1115)
CO (t1975)
Button (t1805)
Hero (t1490)
BB (t775)

Preflop: Hero is SB with J[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/heart.gif[/img].
