JBOSS error - Upgrade 16.2 to 16.3

Question

I have went through the process to upgrade to 16.3 but am receiving an error when starting JBOSS. Error is in server.log. I don't see any information related to this error.

JBWEB000287: Exception sending context initialized event to listener instance of class com.appiancorp.common.config.ConfigurationLoader:

Thanks.

server.log

To add to the previous note, for anyone seeing this error in the future, this is caused specifically by using the web.xml from a previous version of Appian in the installation for 16.3.
