It would also be good if the much less bloated version (for debian/ubuntu servers) of openjdk-7-jre, called openjdk-7-jre-headless would not throw up an error - as requested here
Openfire 3.10 - Debian/Ubuntu and Java 7
Or is there some aspect of the full jre that is used, which was not used on earlier verions of openfire when the jre-headless did work...?
