[ https://issues.jboss.org/browse/JBJCA-1388?page=com.atlassian.jira.plugin... ] Lin Gao updated JBJCA-1388: --------------------------- Description: [org.jboss.jca.core.rar.EndpointImpl.activate|https://github.com/ironjacam...] is setting the TCCL to be that of the resource adapter's ClassLoader, which would be the rar's custom module if the rar is deployed as a JBoss module, however inside this same block it is creating the Bean Validator, so it goes looking for the provider in the rar's module instead of the JBoss IJ module. This would lead to the following exception if the rar is deployed as a module: {code} ERROR [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0215: Failed to resume activity org.jboss.as.ejb3.component.messagedriven.MessageDrivenComponent$1@3f9a21a1.
