On initialization of the GlobalComponentRegistry, component injection attempts to resolve all classes for all methods in the declaration chain of all the components which might require injection.
If we ever want to make some dependency truly optional (and "provided" at the maven dep level), we would need to ignore certain classes and inject nulls where necessary.
