Before every Openfire release, Java JRE should be updated to the latest version (unless it was just released a few days ago, then i think previous to last version should be fine). After closing this ticket, file another, for the next release (clone this ticket).
Update to 1.8.0_162 once available in install4j.
bamboo.igniterealtime.org host updated to 162
bamboo RPM job updated to 162
