Purdue has a nice bulletin on juglone, with a list of plants that are
susceptible to or tolerant of its effects.
Google publication HO-193. Black raspberry is listed as tolerant;
blackberry is not!

Maybe it's the poor sandy soils here, but blackberries usually don't grow
wild in the black walnut sites, while black raspberries do.
sWI, plenty blackberry canes but not much fruit
