WAR deployments fail if EE subsystem removed
--------------------------------------------

                 Key: AS7-2120
                 URL: https://issues.jboss.org/browse/AS7-2120
             Project: Application Server 7
          Issue Type: Bug
          Components: Web
    Affects Versions: 7.1.0.Alpha1, 7.0.2.Final
            Reporter: Tristan Tarrant
            Assignee: Stuart Douglas
            Priority: Minor


If the org.jboss.as.ee extension is removed from the configuration, the deployment of WAR files doesn't work anymore. The following exception is thrown:

Looking at the code, it seems like the NamespaceContextSelector should be injected only if there is a moduleDescription. Unfortunately if it isn't (like in my case), it fails. If the moduleDescription should never be null, then a better exception should be thrown, otherwise the code shouldn't break.
