I have mixed feelings about Java. It's a solid feature set, and I really love how InterruptedException was always a thing, so you can generally terminate a thread and it works (a lot of languages don't do this right). I love checked exceptions.

But the spooky action at a distance type annotation hell, needing builders everywhere because of lack of named parameters, poorly conceived generics, nullability not being first class, lambdas being incompatible with checked exceptions, etc. are a pain.
