grails 3 war in JBoss EAP 6.2.0 does not work

Question

When I try to run a very simple grails 3 (3.0.7) application as war (with embedded tomcat removed) in JBoss EAP 6.2.0.GA (AS 7.3.0.Final-redhat-14) all requests end up in a HTTP 404. The same war works in Tomcat.

Searching the web I found the following related to Spring Boot:

springBoot application on Jboss EAP, servlet context not lodaed

Unfortunately configuring the property server.servlet-path in application.yml (in yml format) did not work.

Looking into the grails 3 source:

https://github.com/grails/grails-core/blob/master/grails-plugin-controllers/src/main/groovy/org/grails/plugins/web/controllers/ControllersGrailsPlugin.groovy#L79

I found the solution. In application.yml add the following configuration:

grails:
    web:
        servlet:
            path: /*

starting with web: into the existing grails: section. Then all requests are working as again as expected.
