Openfire 3.10.2 with openjdk-8 on Debian

I am running Ubuntu Trusty with openjdk-8-jdk. Unfortunately, the Openfire 3.10.2.Debian package still predepends on Java 7. Are there any issues known, when running Openfire under Java 8? Is it possible to update the declared dependency in the Debian package in order to allow installation of Openfire 3.10.x under Java 8. Please have a look to the following file: https://github.com/igniterealtime/Openfire/blob/master/build/debian/control

If we updated the dependency, would this cause issues on older Debian releases?

As far as I understand the packaging, we just have to extend the package predendency and add (not replace) the openjdk and the oracle-java in version 8:

Pre-Depends: openjdk-7-jre-headless | openjdk-7-jre | oracle-java7-jre | openjdk-8-jre-headless | openjdk-8-jre | oracle-java8-jre

But someone, who is much deeper inside die Debian packaging must check if this is a feasible solution.
