Maybe also add this to UnnecessarilyVisible? (as hinted in the TODO comment above the constant)

Added it there as well as to few other places I found. Thanks!
I've seen it also in InjectMatchers and other places that seem to relate to dependency injection / Guice. I didn't change that, because the logic is a bit more complicated, and since we're not using Guice, I'm not that confident in changing those. I'm not sure whether it even supports Jakarta EE already.

FYI, it does!

@tbroyer good to know :) But do you think we can have these checks merged separately from Guice or are they somehow intertwined?
I also noticed that sometimes there are suggested fixes to add javax.inject.Inject annotation, but it doesn't make sense if the project is already using jakarta / Guice 7 🤷 I think there could be some heuristic, but I'm not the best person to define that as we're using spring instead 😅
