My wife went exactly through this situation last year. I had my AOS approved after our marriage and I (due to the stupid advice of my lawyer) filed for her AOS too after her J1 waiver got approved. her AOS was about to be approved by INS !!
But i quickly realized their mistake and got her AOS withdrawn.( also got my money back from lawyers
the problem in such a case,is if at some point in the future ,INS detects this error,it might invalidate your GC.
