I was trying to restart the running ignition service thinking it would be fine but I was unable to. checking the status yields this output. I don't know why `The: not found` is appearing in the output. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/3/c38e53213fdb4d3c3c4e1a73bdb6926a87d641b4.png) The logs are complaining about not creating a JVM or the JVM exited while loading the application ```auto STATUS | wrapper | 2023/03/07 08:30:33 | Launching a JVM...

If it's a configuration problem the only thing I've changed is adding debug info to the ignition.conf for better diagnosing. I have attached my wrapper log, my ignition.conf and the output of `journalctl -xe`. Any help is much appreciated.

The error says this line in your `ignition.conf` is a problem: ```auto wrapper.java.additional.3=-Xloggc:/var/log/ignition/javagc-%WRAPPER_TIME_YYYYMMDDHHIISS%.log ``` ---

Oops, not that one, this one: ```auto wrapper.java.additional.7=-XX:+PrintGCTimeStamps ``` The former one is just deprecated. ---

You may find that all of the last 3 additional GC-related params are no longer supported in JDK 11. ---

yup removed those from the conf and it started no problem. Thanks Kevin!
