--- Additional comment from Nikos Moumoulidis on 2022-03-16 10:24:20 UTC ---

Regarding the javax.el-api-3.0.0.jar not being loaded: it's not loaded simply because tomcat already has this dependency by itself. It is also a transitive dependency (we don't use it directly in candlepin) so we can't (and don't want) to add it to our maven manifest just to mark it as provided. That is also coming form an INFO statement, so I don't see the issue there?

Regarding the Illegal reflective access WARNING. This not a Satellite or Candlepin related issue, but a Tomcat issue. You would have to open a separate bug against Product: "Red Hat Enterprise Linux 7", Component: "tomcat" for that.

We will look into the "com.google.inject" WARNINGs though, since that is definitely Candlepin.
