I honestly don't know much about java, but I guess you don't have real dependancies on the lower versions (As in: no other packages require them)? Then perhaps it's an option to edit the PKGBUILD of these lower versions and modify the name. Something like jdk9-custom etc. Then the higher versions won't conflict. Mvg, Guus Snijders
