Incompatibility with DeltaSpike JSF Module 1.x

Some change in 2.3.3 causes and incompatibility with Apache DeltaSpike's JSF Module. I am not sure yet what exactly causes it, but MyFaces 2.3.2 is NOT affected.

The issue arose on our side, as we noticed @PostConstruct of some of our @ViewScope @Model is called twice.

Mojarra 2.3.8 is NOT affected, which - together with the fact that MyFaces 2.3.2 is not affected either - brings me to the conclusion this is a bug introduced with MyFaces 2.3.3.

I have a minimal project showing the issue, which I will link here shortly.
