I just performed an upgrade from 7.15.0 to 7.16.0 using the Linux installer (as I always have). However, upon server startup, I receive the following:
java.nio.file.NoSuchFileException: /opt/atlassian/confluence/confluence/WEB-INF/lib/lucene-queryparser-4.4.0-atlassian-4.jar
This file does exist but it version "atlassian-6". I already tried clearing the plugin cache and this did not resolve the issue.
Update:
It appears as though I can get the server to start if I copy the WEB-INF/libs folder from a backup copy of my 7.15 libs, but then none of the content actually appears normally. In addition, even though 7.16 is installed, it still generates in the footer that it's running "7.15".
