So you agree that many people were absolutely "running away from C and C++ to Java/C#" but somehow this didn't involve any data processing code, even though arguably the main thing that internally-developed enterprise code does is data processing of some kind? OK, I guess.
> Which C or C++ engines exactly got rewritten to Java?
It's difficult to give names precisely because private enterprise development was involved. But essentially every non-trivial Java project starting from the mid-1990s or so, would've been written in C++ if it had been around in the late 1980s or earlier in the 1990s. It's just not very sensible to suppose that "data processing" as a broad area was somehow exempted from this. And if writing segfault-free code in C/C++ could be dismissed as a mere "skill issue" we wouldn't need Rust either. It's a wrong take today and it was just as wrong back then.
(And yes, Java took significant steps forward in safety, including adding a GC - which means no wild pointers or double-free issues - and converting "null pointer" dereferences into a properly managed failure, with backtraces and all that. Just because the "safety" vocabulary wasn't around back then except for programming-theory experts, doesn't imply that people wouldn't care just as much about a guarantee of code being free from the old segfault errors.)
