Hello kaffe people, Congratulations on kaffe-1.0.7 release! anyway, I found a issue in kaffe.def, there are same descriptions; check_null(PUTFIELD, stack(1), 37); check_null makes a label by 1st arg and 3rd arg, so they make same labels. please, confirm. Thank you, Suzuki, Ryouzaburou ryos at sinby.com http://www.sinby.com
