--> can you provide a link to that discussion please?
I found out that it was a private communication. I'll find a way to pass it to you.
--> Can you clarify this a bit? Did you check if resteasy's jboss-modules module is properly replacing resteasy-spring the way it does with other components?
yes, the resteasy-spring is not being properly replaced.
The directory "Resteasy/testsuite/integration-tests-spring/deployment/target/test-server/wildfly-10.0.0.Final/modules/system/layers/base/org/jboss/resteasy/resteasy-spring/main/bundled/resteasy-spring-jar" contains the "resteasy-spring.jar" and "resteasy-spring-3.0.14.Final.jar". I think the resteasy-spring.jar is used which does not contain the latest version.
In WF "wildfly-11.0.0.Alpha1-SNAPSHOT/modules/system/layers/base/org/jboss/resteasy/resteasy-spring/main/bundled/resteasy-spring-jar" contains only the "resteasy-spring-3.0.19.Final.jar".
