Mark Struberg commented on CDI-616:
-----------------------------------

> Do nothing but add clarification in the spec : Injection in transient field is not supported. 

We probably are talking about thesame thing, but the wording is not quite as discussed on the ML as far as I interpret it.
Why should the injection itself not be supported? I think what we agreed on is that we just don't do anything for RE-injecting it in case of deserialisation. 
At least that was I understood during our discussion. Not sure we need to clarify anything as this is standard Java behaviour: the developer is responsible to get back any transient fields himself by default.

> An injection point declared as 'transient' is not useful, due to the fact of after bean's passivation, the transient field will not be reinjected and its value will be lost. This causes confusion. See Weld forum discussion [link title|https://developer.jboss.org/thread/179486]. In the section 5.5.7, how about to make the following changes?
> The isTransient() method returns true if the injection point is a transient field, and
> false otherwise. If the injection point represents a dynamically obtained instance then the
> isTransient() method returns true if the Instance injection point is a transient field, and
> false otherwise.
> =>
> The isTransient() method returns true if the injection point is a transient field, and
> false otherwise. If the injection point represents a dynamically obtained instance then the
> isTransient() method returns true if the Instance injection point is a transient field, and
> false otherwise. If this injection point is declared as transient, after bean's passivation, the value will not be restored. Instance injection point is the preferred approach.
> Any other better suggestions?
