That module defined on custom-handler looks wrong. I think it should likely be org.apache.kafka.log4jappender.

Do you have -Xbootclasspath/a stuff involving logging in the VM launch command? On Wed, Sep 18, 2019 at 10:48 AM Dustin Kut Moy Cheung <dcheung(a)redhat.com&gt; wrote: > Thanks for the suggestion!

Yup I do have some logging stuff: -Xbootclasspath/a:/opt/eap/modules/system/layers/base/.overlays/layer-base-jboss-eap-7.2.3.CP/org/jboss/logmanager/main/jboss-logmanager-2.1.7.Final-redhat-00001.jar:/opt/eap/modules/system/layers/base/org/glassfish/javax/json/main/javax.json-1.1.2.redhat-1.jar:/opt/eap/modules/system/layers/base/javax/json/api/main/javax.json-api-1.1.2.redhat-1.jar:/opt/eap/modules/system/layers/base/.overlays/layer-base-jboss-eap-7.2.3.CP/org/wildfly/common/main/wildfly-common-1.5.1.Final-redhat-00001.jar The additional files that I add to the modules folder is here: https://paste.fedoraproject.org/paste/y2xf5u5nq3iL18pQOkAlNQ Let me know if I should create an EAP or a Wildfly issue!
