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.
