             Summary: Clarification needed on Set mutability returned by SPI
                 Key: CDI-584
                 URL: https://issues.jboss.org/browse/CDI-584
             Project: CDI Specification Issues
          Issue Type: Clarification
          Components: Portable Extensions
            Reporter: Antoine Sabot-Durand

{{ProcessBean}} lifecycle event could be the occasion to add new Injection point to an existing bean, but when you call {{ProcessBean#getBean()#getInjectionPoints()}} the returned set mutable in OWB and immutable in Weld.
As the spec doesn't precise if the Set should be mutable or not, each spec made its own choice.
The result is a lack of consistency between both impl and an interesting feature harder to do with Weld (work with AnnotatedType or create a custom bean to add injection point)

More generally we should clarify mutability of each Set returned in the SPI. And check if it wouldn't be better to add method to life cycle event to provide a "temporary" mutable set (i.e. {{ProcessBean#getInjectionPoints()}}
