Cause

The following file within the Wildfly modules folders appears to be causing problems:

\modules\system\layers\base\org\apache\logging\log4j\api\main\log4j-api-2.14.0.jar

Resolution

Please do the following:

1. Stop Wildfly
2. Rename the Wildfly \modules\system\layers\base\org\apache\logging\log4j\api\main\log4j-api-2.14.0.jar to log4j-api-2.14.0.jar.bak
3. Delete the contents within Wildfly standalone\log and Wildfly standalone\tmp folders
4. Rename the Wildfly standlong\deployment marker files so you have castyles5.1.1.ear.dodeploy and iam_im.ear.dodeploy in that folder
5. Start Wildfly
