Are ice-java-devel and ice-java subpackages of the same build? If yes,
you can use slice2java within one specfile. If not, then the naming is
a bit awkward, but what would stop you from using BuildRequires:
ice-java-devel in ice-java? Or is ice-java-devel dependent on
ice-java, e.g. you have a circular build dependency, e.g. a
bootstraping problem?

If it's a bootstraping problem, either do ice-java and ice-java-devel
in one source package, so no build dependencies to external packages
arise, or if that's not an option you need some special bootstraping
attendance by both the FPC and the build admins.
