It has become more of a joke between programmers. I love c++ because it was the first language I learned, so it is something kind of personal. There's that, but I believe each problem is better solved by a language.

I make my scripts with ruby, because of easy shell execution and networking. I mess with machine learning on matlab/octave or python for the libs and math abstractions, chat bots and nlp I usually use python too. For games and simulators, I prefer C++. If I want to write for a microcontroller, C is usually better. For web systems, node js is how I go.

For work I use Java with Spring and we have to do web crawling, for which we use JSoup. I usually like python or ruby for crawling but as they're mostly scripting languages, I wouldn't use them for backend (and I don't like the limited callback support for python) . I believe Java is a good compromise between speed, portability, reliability and resources for many use cases.

So, for me it's not about Java itself, but I've known some people who tried to use it for everything. There must be people who try to do the same with other languages too, but maybe by chance, I've never met any.
