JSF internal weapon stores

Does anyone know how many A-A missiles the JSF will be able to carry -internally-?

From the videos of the Boeing X-32A its evident that it can carry 2 JDAM along with 2 AIM120, but does this mean it can carry a max of 4 AIM120 (and no AIM9)? Or 2 AIM120 and 2 AIM9?

I know pylons can be fitted to the JSF but that would greatly hamper its stealth advantage.
