How reproducible:

Start/Restart tomcat service.


Steps to Reproduce:
1. systemctl restart tomcat

Actual results:
Jul 15 12:47:18 satellite.example.com server[6103]: WARNING: An illegal reflective access operation has occurred
Jul 15 12:47:18 satellite.example.com server[6103]: WARNING: Illegal reflective access by org.apache.catalina.loader.WebappClassLoaderBase$1 (file:/usr/share/java/tomcat/catalina.jar) to method java.lang.ClassLoader.registerAsParallelCapable()

Jul 15 12:47:18 satellite.example.com server[6103]: WARNING: All illegal access operations will be denied in a future release

Expected results:
No Warnings (at least contain illegal word)
Comment 3 Nikos Moumoulidis 2022-07-29 11:11:02 UTC 
If you want to suppress these warnings (which are benign), just add append the options '--add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED' to the JAVA_OPTS property in /etc/tomcat/tomcat.conf.

Moving this to the installer component since that is where the tomcat configuration lives.
