[BUG] Upgrade error

[benoiton]

When I try to upgrade a 6.10 database to 9.0 (either from WebUI or from ant), I get an error.

ERROR org.ejbca.ui.cli.UpgradeCommand - Post Upgrade not performed, see server log for details.

In server.log, the stack trace begins with:

 ERROR [org.ejbca.core.ejb.upgrade.UpgradeSessionBean] (default task-2) Unexpected error from post-upgrade: java.lang.ClassCastException: class org.jboss.logmanager.log4j.JBossLogger cannot be cast to class org.apache.logging.log4j.core.Logger (org.jboss.logmanager.log4j.JBossLogger is in unnamed module of loader '[email protected]' @56d4bd5b; org.apache.logging.log4j.core.Logger is in unnamed module of loader 'deployment.ejbca.ear' @71231573): jakarta.ejb.EJBException: java.lang.ClassCastException: class org.jboss.logmanager.log4j.JBossLogger cannot be cast to class org.apache.logging.log4j.core.Logger (org.jboss.logmanager.log4j.JBossLogger is in unnamed module of loader '[email protected]' @56d4bd5b; org.apache.logging.log4j.core.Logger is in unnamed module of loader 'deployment.ejbca.ear' @71231573)

Searching the web, I found there was some change in logging (l4j) in recent WildFly versions. Following hints, I tried to exclude org.apache.logging.log4j.api in src/deploy/ear/META-INF/jboss-deployment-structure.xml:

<exclusions>
    <module name="org.apache.logging.log4j.api" />
</exclusions>

After ant build deployear + restart, ant upgrade succeed, and the application seems to be still OK.

Tech stack:

• EJBCA r9.0 CE
• WildFly 32
• PostgreSQL 16
• Rocky Linux 9.5
