My point was, HFT is possible to do with something other than C++. Jane Street does OCaml, and you have just cited Java (garbage collection and virtual machine!). Since C++ is such a Chtuloid horror, the mere fact that it is possible to use other language, let alone garbage collected languages, is extremely strong evidence that C++ simply isn't the best choice. You haven't refuted my point, you have supported it.
(Of course, I don't take legacy code nor talent availability into account. They are crucial in any real-world decision, but they don't influence the virtues of the language itself.)
