Sure, but I think it would need some doing. AFAIR the code determines the 
access type
and from then on just reflects on either fields or methods. Maybe as a 
performance 
optimisation as well. Not sure. I agree having some warning for the case you 
describe 
is a good idea, but don't expect this to be a one lines in the code.

That said, things would be easier with Jandex. There it would be easier to 
determine 
inconsistent configuration. I seem to vaguely recall that I might even have 
done though
when working in the metamodel branch. 

Personally I'd probably address this in conjunction with a re-write of the 
mapping code
and switch to Jandex. I think that is still somewhere on the horizon.

If not, it is for sure feasible, just take quite some effort.

Right, that's a usual mistake.

I don't think you need to be super-deep into ORM/JPA to understand that.
There are warnings and notes about this everywhere.

For sure, but as said, I'd tackle this as part of a bigger refactoring.
