Maybe this is it. How can I do that for any instance of "Molecule"?
I added the follwing lines (Ruby code)
---
iterator = finder.findAllRings(@mol).atomContainers.iterator
while iterator.hasNext
        ring = iterator.next
        Aromaticity::AromaticityCalculator.isAromatic(ring, @mol)
end
---
to the calculation, it just returns true for Aspirin. How can I set the
aromaticity? Am I missing some point?

Hm, can't find this class in the jchempaint-primary branch. Is it in the
1.2.x? If so, I'll wait until you merged the patches in master.

Thanks again for the fast response
