I have never heard or even -heard of- any scholar of Islam claim that it is unlawful, be it a true Muslim scholar or a scholar in the academic sense. The aspect of caffeine that is questionable, in my opinion, with regards to legality in Islam is its markedly negative effects on the cardiovascular system. But that's just IMO.
