I had some involvement with development of an air traffic management system, which was being written in Java, as that was certified for use in that field. As a language, I'd rather use C++ over Java, but if safety criticality were the priority, I'd choose Java every time. I haven't coded in Ada but unless there's something about it that's truly awful to work with, it seems a better choice than C/C++ from what I know about it.
