Maybe I'm missing something, but have been unsuccessfully trying to track down a solution for my issue...

So I'm running from a WAR file, been successfuly running on 2.479.3 LTS until now, but have failed to run either of the two latest LTS versions listed in the issue title.

What I get is this:

Service failed to startup due to timeout

I've checked sha256 sum, it was fine.
I've tried setting TimeoutStartUSec=5min but didn't help, it was the same.

This is my startup line:

/usr/bin/java -XX:InitialRAMPercentage=50.0 -XX:MaxRAMPercentage=50.0 -XX:+UseG1GC -Djava.awt.headless=true -jar /usr/share/java/jenkins.war --webroot=/var/cache/jenkins/war

If you need further info, just let me know.

Any help is much appreciated, thanks!
