Re: Upgrade to XWiki 16.0.0 broken on Ubuntu 20.04 I solved the issue.  Apparently even though my system was setup to use Java 17, I still had Java 11 available.  My */etc/default/tomcat9* file didn't explicitly specify JAVA_HOME.  So apparently XWiki Tomcat just picked Java 11 as the first one it encountered in `/usr/lib/jvm` rather than use the system's active version of Java as reported by `java --version` . I added the line `JAVA_HOME=/usr/lib/jvm/java-1.17.0-openjdk-amd64` and now it's working. Add Comment
