IllegalStateException: No ConfigProviderResolver implementation found --------------------------------------------------------------------- Key: WFWIP-64 URL: https://issues.jboss.org/browse/WFWIP-64 Project: WildFly WIP Issue Type: Bug Components: MP Config Environment: git@github.com:jmesnil/wildfly.git:WFLY-10522_microprofile-config-smallrye_extension Reporter: Jan Stourac Assignee: Jeff Mesnil Priority: Critical Attachments: MicroProfileConfigTestCase.war There is following IllegalStateException printed during the server shutdown when an application which utilizes microprofile-config-smallrye subsystem is deployed: {code} 16:06:45,862 ERROR [org.jboss.as.server.deployment] (MSC service thread 1-7) WFLYSRV0043: Deployment unit processor org.wildfly.extension.microprofile.config.smallrye.deployment.SubsystemDeploymentProcessor@2e89bd6f unexpectedly threw an exception during undeploy phase POST_MODULE of deployment "MicroProfileConfigTestCase.war": java.lang.IllegalStateException: No ConfigProviderResolver implementation found! at org.eclipse.microprofile.config.spi.ConfigProviderResolver.instance(ConfigProviderResolver.java:122) at org.wildfly.extension.microprofile.config.smallrye.deployment.SubsystemDeploymentProcessor.undeploy(SubsystemDeploymentProcessor.java:109) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.safeUndeploy(DeploymentUnitPhaseService.java:211) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.stop(DeploymentUnitPhaseService.java:204) at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:1792) at org.jboss.msc.service.ServiceControllerImpl$StopTask.execute(ServiceControllerImpl.java:1761) at org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1556) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1985) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1487) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1378) at java.lang.Thread.run(Thread.java:748) {code} Looks like there is missing implementation for {{ConfigProviderResolver}} abstract class? The application [^MicroProfileConfigTestCase.war] is quite simple and almost same as one used in [this test|https://github.com/jmesnil/wildfly/blob/55a2c220206abc9ca3b6550df988...].
