NoClassDefFoundError deploying WAR to wildfly 18

Description

When trying to deploy I get various stack traces about classes not found. Seemingly all related to originating with the "org.reactivestreams.Publisher" class not being found.

I do not get the error with Geoserver 2.15.3.

I originally hit the error with an older Wildfly, version 10, and I attempted to upgrade to version 18 to see if it would resolve the issue but it does not.

Environment

Wildfly 18.0.1.Final
