I am setting up SonarQube 8.9.10 (believe the last version supporting Java 11) in RHEL8. After setup everything, when I start, I get the following exception in web.log

2023.03.15 17:33:59 WARN  web[][o.a.c.l.WebappClassLoaderBase] Failed to clear soft references from ObjectStreamClass$Caches for web application [sonar]

Hi,

Welcome to the community.

SonarQube 8.9.10 is now officially EOL. Especially since you’re just getting started, you should be working with SonarQube 9.9 LTS. Please let us know if you continue to have problems with the new version.

Note that SonarQube 9.9 requires Java 17.
