This is probably more of a hotspot-dev or hotspot-runtime-dev kind of question,
rather than core-libs.

I think BytecodeInterpreter is part of CppInterpreter, which I think
is only used by Zero platforms, with the TemplateInterpreter used by
all other platforms. So unless you are running on a platform that
uses Zero, or specifically built for Zero, I think BytecodeInterpreter
won't be used (and might not even be compiled in?).
