CMBilling.jar "while processing cn/cmgame/leaderboard/api/GameLeaderboard.class", "dx tool failed: UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dx.cf.code.SimException: bad range: 5..6; actual size 5"

I've just created a new ANE for CMBilling.jar (a common library for implementing IAP in China), and I get the error below, 100% of the time, if I try to package an apk with it included.

I created a repo for easy access, SixMinute/ANEMyGamez · GitHub but realistically, if you want to replicate the bug, just include ANEMyGamez/ANEMyGamez.ane at master · SixMinute/ANEMyGamez · GitHub as an ANE into an Android project, then try build, and you'll get the same.  I've tried with both AIR 14 SDK, and AIR 15 beta.

dx tool failed:
