[keycloak-dev] Keycloak Wildfly adapter question

Hi all, I already have Wildfly 8.1.0.Final installed, and try to install Keycloak war distribtion 1.1.0.Beta2. When deploying the client Keycload Wildfly adapter dist 1.1.0.Beta2 to Wildfly, I notice that the adapter overrides the some Wildfly module file to use different jar file than the one provided by Wildfly. In particular, 1. the file ../modules/system/layers/base/org/jboss/as/cli/main/module.xml is replaced to use wildfly-cli-1.0.0.Alpha12.jar instead of the provided file wildfly-cli-8.1.0.Final.jar. 2. The file ../modules/system/layers/base/org/jboss/aesh/main/module.xml is replaced to use aesh-0.33.12.jar instead of the Wildfly provided file ash-0.33.11.jar My question are: 1. What is the difference of the Wildfly provided jar files and the Keycloak ones? 2. Why Keycloak uses a different files than the one provided by the Wildfly distribution? 3. Is there any impact if I uses the Wildfly provided jar files instead of the Keycloak one? Thanks.
