on the bubble with aa preflop

[b112895]

playing a po tourney on the bubble with aa preflop
i raise a bb
folds around to big blind
guy in the bb calls

flop j94

its a rainbow

i have like 12 bbs left
bb starts and he raises like 8 bb
i go all in
i do this because it seems logical and the guy seems pretty loose, however i really had no idea what he had, i couldnt put him on aj or worse, so i think i knew he had me, but i called anyway. i have to aa so i might as well as take a shot.
guy shows j9
im out in 11th
for some reason i felt like this was going to happen
i really believed i was going to be mister bubble boy
but its kind of weird i think that he raises so much,
dont you think he wants value?
i mean with j9 i think he should know that his hand is good, if i had a set he wouldnt get me to fold it lol, idk i dont really get why certain players do things
well i can ask what would you do, but i think anybody would have shoved there
