JGROUPS_ENCRYPT_SECRET env variable was defined in EAP 7.4 templates and used to mount the keystore: https://github.com/jboss-container-images/jboss-eap-openshift-templates/blob/eap74-dev/templates/eap74-https-s2i.json#L720 but also checked in the jgroups launch script: https://github.com/wildfly/wildfly-cekit-modules/blob/main/jboss/container/wildfly/launch/jgroups/added/launch/jgroups.sh#L256 . In EAP 8 s2i V2, we don't have templates anymore, we rely on helm charts. Relying on the existence of this secret name env variable is wrong.

We shouldn't check for the existence of this env variable in launch script nor print warning that mention it.
