[weld-dev] Injection Services cannot handler producer on a static field

[Martin Kouba]

Hi Emily,

for a static producer field there is no InjectionTarget (there's no 
instance to inject) and therefore no IT may be registered via 
InjectionServices.

When using InjectionServices the current API does not allow to bypass 
the value of the static field and obtain the EE resource (e.g. do a JNDI 
lookup). So we let the integrator "inject" the static field, then read 
the value and propagate as the bean instance.
