probably made a mistake here....or did I?

I have 22 in MP2, in the money with 18 people left out of 130. I have 7600 in chips with the blinds at 300/600. MP1 is all in on the antes with just 22 chips left. I figure I will call the 600 after everyone else folds and go heads up with his overcards and possibly flop a set vs. bb. The other shortstack, who is on the button, goes all in for a total of 2500. I figure I'm calling 1900 to win 6500, so I have to call. I do. Board runs out of KQJQ3 and he flips up AK and the shorter all in flips up Q5 to take down the pot. Railbird commented that it's a huge mistake to have called with 22 in that sitaution and lost 2.5k of my 7.6k stack.

Did I misplay this? Should I have just mucked it? The shortstack who had 22 chips ended up winning five all ins in a row to build it up to 6k and I was out with AQ vs. AK just a few hands later.
