Use jlongFromPointer instead.

I would have to set the libjingle_peerconnection_jni as dep if i like to use
this function.
Seams a bit of overkill to me.

Or should we move this helper function in to a separate target so that i don't
have to link the libjingle_peerconnection_jni ?

Ok, then it's an overkill. Let's go with reinterpret_cast.
