What's weird is that every app in Java uses a DI container, while just about no apps that I've encountered in the rest of the world worry about anything that heavy. Most apps just cheat and use a bit of global state or maybe roll their own service locator pattern and don't worry about it. From the outside it seems like Java's sweet spot is really massive applications where you can't just cheat in one or two well-known spots in the code and call it good.

The sad thing is that DI doesn't need to be heavy. I looked into this for some projects I was planning, and there are some lightweight (if technically off-putting, IMO - see Dagger 2 syntax) ways to achieve this. But everyone just reaches for the big frameworks in the first instance.
