This fedora package installs java-atk-wrapper in a JRE-independent way. It is
up to each JRE to make use of it correctly. In general, you want to symlink the
shared object and the jar into somehwere where the JRE can find it and
configure the accessiblity configuration of the JRE to load this.

For OpenJDK, the process looks like this:
ln -s %{_libdir}/java-atk-wrapper/libatk-wrapper.so.0 \
    /usr/lib/jvm/jre/lib/%{arch}/libatk-wrapper.so
ln -s %{_libdir}/java-atk-wrapper/java-atk-wrapper.jar \
    /usr/lib/jvm/jre/lib/ext/
echo "assistive_technologies=org.GNOME.Accessibility.AtkWrapper" \
    >>  /usr/lib/java/jre/lib/accessibility.properties
