Hello @jblaine,

I’ve just tried on Ubuntu 18 LTS / Java 11.0.2 with SonarQube Community Edition 7.9.1 and SonarJava 5.14.0.18788 and SonarQube is starting without a problem.

I suggest 2 things:

- download a fresh SQ CE 7.9.1 and try to upgrade SonarJava to 5.14 to see if you reproduce the problem on a vanilla installation
- revert SonarJava to 5.13 on the instance where you have the failure and share the [System Info](https://docs.sonarqube.org/latest/instance-administration/system-info/) file: this way we will see the plugins installed and in particular if you have custom plugins

Alex

Hi Alex, I can’t reproduce this now. I’m not sure what happened to get the SQ instance into that weird state where Sonar Java 5.14.018788 wouldn’t work, but everything is fine now. Thanks for trying to reproduce this.
