[cdi-dev] [JBoss JIRA] (CDI-360) NormalScoped Bean<T> should all be forced to implement PassivationCapable

[Pete Muir (JIRA)]

    [ https://issues.jboss.org/browse/CDI-360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12764006#comment-12764006 ] 

Pete Muir commented on CDI-360:
-------------------------------

An option would be to say that custom beans are not passivation capable dependencies unless they implement PassivationCapable which avoids breaking apps unnecessarily, and add a note to the spec that we recommend all Beans implement PassivationCapable. Then perhaps in CDI.next require it.

> When serializing a Contextual Reference of a CDI bean, we need to transport over it's proxy. This proxy internally need to serialize it's Bean<T>. But this is only really possible if the Bean implements PassivationCapable. Any attempt to use the type + qualifier is doomed to fail, as this still leaves room for clashes. E.g. if an Extension registers multiple Bean<T> with Object.class and @Default qualifier but a different name (kind of Spring XML style).
> 6.6.2 comes most close to this requirement, though it doesn't really define that all NormalScoped beans really need to implement PassivationCapable. At least it seems to point into the right direction - but it's nowhere near a clear definition.
> We should force Containers to check whether Bean<T> which serve a NormalScoped scope do implement PassivationCapable.
