Thanks Lukasz for the inputs. I am using S2 DI because i am doing it for my plugin.
For Plugin to work with different implementations my intentions let user specify the provider class at configuration time and based on the user provider class i want to init the plugin mechanism. Only information i was having that all provider classes will have to extends MyClass and there are not any specific set of classes which implements MyClass. So i was trying to make the provider inside my plugin a more generic which should be capable enough to hook itself with any provider which satisfy the contact ( <? extends MyClass> ) is there any way to do this with S2 internals?
