Martin Kouba commented on CDI-45:
---------------------------------

Note that {{Optional}} is not {{Serializable}} and is defined final. So there will be problems with injecting into beans with passivating scope (e.g. {{@SessionScoped}}).

> There are occoasions where it may be useful for some injection points to be optional, e.g.
> @Inject
> @Optional 
> MyBean bean; 
> This would behave the same as a normal injection point, however it will not cause the deployment to fail if it is not satisified.
