Since the rest of the jakarta projects are gradually getting the jakarta- prefix.
dev-java/jakarta-oro imported and references updated. same thing as for jakarta-regexp, jakarta-oro imported and marked as ~arch. i've revision bumped all ebuilds which were marked stable on atleast one arch and had oro as a dependency. the reference was updated in the unstable revision bump. therefor, oro has to stay in the tree until we can mark jakarta-oro as stable. when the time has come, i'll update all references again and afterwards i'll remove dev-java/oro from the tree. marking this one as fixed.
