Singleton is not set exception for extension observer of BeforeShutdown event
-----------------------------------------------------------------------------

                 Key: WELD-891
                 URL: https://issues.jboss.org/browse/WELD-891
             Project: Weld
          Issue Type: Bug
          Components: Events
    Affects Versions: 1.1.1.Final
         Environment: Weld SE
            Reporter: Aaron Anderson
         Attachments: weldext.zip

When updating to Weld 1.1.1.Final from Weld 1.1.0.Final (this version works fine) the following exception is thrown during a Weld shutdown() invocation:


225509 [main] ERROR org.jboss.weld.Bootstrap - Exception(s) thrown during observ
er of BeforeShutdown

Running the code through a debugger it looks like my CDI extension, which is not annotated with a scope annotation, is being placed in the ApplicationScope context but when Weld shutdowns the following code is invoked

WeldBootstrap line 490:

            try
            {
               applicationContext.invalidate();
               BeforeShutdownImpl.fire(deploymentManager, beanDeployments);
            }

which invalidates the context the extension exists in before invoking the shutdown event on the extension thus causing the exception.

Please download and run the attached maven example by running mvn clean test
