This so much!

simplicity is underrated and unfortunately esp. young devs are proud when they are capable to build complex systems.

After working extensively with plugin architectures like OSGi an learning about functional programming I am deeply skeptical when somebody mentions plugin systems and IoC containers.

I've just recently started using Java 8 on the job and what's really jumped out at me is the slight of hand of the Function interface. By simply creating a generic interface called Function and "tricking" developers into coding to an interface things like IOC containers and mocking libraries are no longer needed.

I don't need Spring to auto wire in dependencies in order to simplify testing. In my test class I can just whip up whatever dummy implementation I want and create add a constructor for the Unit Under Test to inject that implementation manually.

The other thing that's been rolling around in my mind using Java 8 with the Function interface is; if you want to expose architecture issues and other warts in the code base, disallow the use of mocking test frameworks.
