Privet,
To me, the former could mean classes where the teacher speaks French but where (s)he does not necessarily teach the French language.

No ambiguity and no frequent usage either.

The former simply states the language of instruction and not the subject. There are French speaking schools around the world, they can teach physics in French or philosophy in French. The latter indicates that it is French that is being taught, the instruction could be in English.

How about 'classes of French'?

Doesn't work. Substitute classes of mathematics etc. You could say "He's been attending classes studying French".

[konungursvia]

If you mean classes whose purpose is to learn French, say "taking French classes".

If you mean all other types of class, e.g. history, math, in French, say "taking classes in French."

They are both somewhat ambiguous, but the usages suggested are more clear than any others.

Well, I am taking French language classes at the local university.
