Stefan Seifert commented on SLING-3863:
---------------------------------------

why? the field/parameter is marked explicitly as "@Optional", so failing the 
injection is not what the user expects.

> Sling Models: Injections fails for optional primitive types without default 
> values

> Sling models injections for interfaces and constructor fails if:
> * the type to inject is a primitive type
> * its marked as optional
> * and there is no value to inject
> in this case it is tried to inject null which fails because null is not 
> allowed for a primitive.
> patch attached.
