---------------------------------------

             Summary: Unexpected exception thrown when FlowMap is injected on a RequestScoped bean
                 Key: MYFACES-4127
                 URL: https://issues.apache.org/jira/browse/MYFACES-4127
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 2.3.0-beta
            Reporter: Eduardo Breijo
            Priority: Minor


When @FlowMap is injected on a RequestScoped bean, and you try to use that object (which should be null since we are not inside of a flow), an unexpected exception is thrown.

Caused by: org.jboss.weld.exceptions.IllegalProductException: WELD-000052: Cannot return null from a non-dependent producer method: Producer for Producer Method [Map<Object, Object>] with qualifiers [@FlowMap @Any] declared as [[UnbackedAnnotatedMethod] @Produces @FlowMap @ApplicationScoped public org.apache.myfaces.cdi.faces.ApplicationScopeObjectProducer.getFlowMap()] declared on Managed Bean [class org.apache.myfaces.cdi.faces.ApplicationScopeObjectProducer] with qualifiers [@Any @Default]
	at org.apache.myfaces.cdi.faces.ApplicationScopeObjectProducer.getFlowMap(ApplicationScopeObjectProducer.java:73)
  StackTrace:

On Mojarra 2.3, we get a different exception which looks more appropriate.
