All of V8 is compiled with -fno-exceptions, so it doesn't support C++ exceptions. You could try building without that flag, but then you'd be entirely on your own you find that something doesn't work (and I'm pretty sure that something wouldn't work -- V8 code is not written to be exception safe).
The exception system that V8 implements for JavaScript code (via Isolate::ThrowException, v8::TryCatch, etc) is completely unrelated to C++ exceptions.
