Description
Testing some of the quickstarts against WildFly upstream, I see this exception during application undeployment for many application:
14:58:56,111 WARN [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000004: Failure during stop of service jboss.undertow.deployment.default-host./jboss-as-ejb-throws-exception-web: java.lang.IllegalStateException: JBAS016071: Singleton not set for ModuleClassLoader for Module "org.wildfly.extension.undertow:main" from local module loader @294944 (finder: local module finder @8923f5 (roots: /jbossas/as7/wildfly/build/target/wildfly-8.0.0.Alpha1-SNAPSHOT/modules,/jbossas/as7/wildfly/build/target/wildfly-8.0.0.Alpha1-SNAPSHOT/modules/system/layers/base)).

I haven't yet investigated what the problem is. It doesn't seem to be causing any problems except for this log. An example quickstart to test is here https://github.com/jaikiran/quickstart/tree/wildfly-upgrade/greeter (start the server, deploy that app and then stop the server to see that exception log)
