------------------------------------------------
According to this log
1) websocket channel was closed in browser
2) the installation itself is corrupted "Caused by:
java.nio.file.NoSuchFileException:
/opt/rooms/webapps/openmeetings/WEB-INF/lib/commons-text-1.9.jar"
Are you sure you have stopped OM before upgrade? :)
