Lately I installed Pade plugin on my openfire sever which runs on raspberrypi 3B. I encountered an error that the focus account, Jitsi Colibri Focus (Jicofo), cannot run. Somehow I started to suspect that the java version may have something to do with it.
I changed the openjdk-8-jdk to JDK11 by downloading from https://bell-sw.com/ (there is limited resource available for armhf platform). I got the pade meeting finally working.
I wonder, if there is a requirement by Pade plugin for Java?
