Antoine Sabot-Durand commented on CDI-377:

To sum up regarding {{@Singleton}} and other {{@Scope}} management, we have 3 options.

# *Stop supporting them in CDI*
   Not possible IMO due to JSR 330 support and other bad side effects ({{@Dependent}} is annotated with {{@Scope}})
# *Remove them from the list of bean defining annotations list*
   So by default ({{annotated}} bean-discovery-mode) classes with these Annotation wouldn't be considered as bean. {{@Dependent}} should be an exception. They would always be beans in {{all}} bean-discovery-mode. Perhaps the more consistent approach regarding mixing CDI and other JSR-330 beans in the same archive :  allow me to have my Guice beans with {{@Singleton}} and CDI beans with CDI scopes living together. 
# *Remove them from the list of bean defining annotations list unless one or more classes in the same archive are annotated with a {{@Dependent}} or any Normal Scope annotation*
   In this case they wouldn't make their archive an implicit bean archive when they are alone. In the case of mixing JSR-330 beans and CDI beans the dev would have to explicitly put a {{@Vetoed}} on non CDI beans to avoid CDI treating them.

> The jsr-330 dependency injection annotations (javax.inject.*) find use in javase environments using IOC packages like guice.
> Adding a dependency on a jar that uses guice or whatever in a javase environment
> to a war deployed to a jee7 container 
> results in CDI processing annotated classes intended for 
> app-managed injection.  See this ticket filed with guava for a concrete example:
