Yeah, Java can run maybe half as fast as equivalently complex C, while being far more maintainable. But to see that kind of performance, you'll want to use POJOs (plain old Java objects), not that enterprise bullshit. And there are many other optimization techniques that your average Java coder wouldn't see in their average coding job. I've been there, didn't like it. If I'm going to be dropping down to C for the hot spots, I'd rather use Python.
Schedule-driven development by people with no domain knowledge, with poorly understood requirements and life-and-limb-critical outcomes, led by an unpredictable moron. What could go wrong?
I wouldn't assume that Java is only half as fast as C for every workload. It's probably a lot closer than you think in a lot of real world scenarios.
