indeed, this hint enabled me to make a spec file that builds both
with gcj and openjdk (see also http://bugzilla.redhat.com/498964#c2):

BuildRequires: java-devel
[...]
for i in -I/usr/lib/jvm/java/include{,/linux}; do
      java_inc="$java_inc $i"
done
%configure CPPFLAGS="$java_inc"

Perhaps this could be part of Packaging:Java; I'm going to mail this
suggestion to fedora-packaging.
