Deltaspike servlet module- IllegalProductException on Websphere 8.5.5.1 (Liberty profile) on startup

[Justin Walsh]

Hi,

I'm using the Deltaspike servlet module successfully on JBoss EAP 6.2.
The same deployment (WAR) fails on startup when deployed on
Websphere 8.5.5.1 (Liberty profile)

This is the error

[4/27/14 10:09:00:432 CEST] 00000025

It would appear as if apache webbeans takes exception to this method
in ServletObjectProducer
<https://github.com/apache/deltaspike/blob/master/deltaspike/modules/servlet/impl/src/main/java/org/apache/deltaspike/servlet/impl/produce/ServletObjectProducer.java>
as HttpSession (the return type) is not Serializable


    @Produces

    @DeltaSpike

    @SessionScoped

    public HttpSession getHttpSession()
    {
    ...

    }

Is this an issue with apache webbeans or should all return types of
SessionScoped producers be Serializable?

Regards
Justin
