alt Hacker NewsJava (w/ the JIT warmed up) could possibly be faster than C++, if the C++ program were to allocate every single value on the heap.
But you're never going to encounter a C++ program that does that, since it makes no sense.

Entertaining anecdote:
I once worked on a python program that was transpiled to C++, and literally every variable was heap allocated (because that's what python does). It was still on the order of 200x faster than python IIRC.
