Thanks. Looks good.


There are two things that are unusual to my taste, but they do not
affect the outcome. Just noting. It is not an objection.

1) Behaviour of getCompatibleType(..) when
resource.getInjectionTargets() is empty.

It always returns null.

This concern does not matter though - It is never called with empty
getInjectionTargets() as that is checked before the call.

2) Assignment


If typeClass != null it looks strange to change the value.
This concern does not matter though - In that case the new value is
the same as the old one.
