This is probably not an issue of the TeX engine, but the package version for the newtxtt font.

I'll check that and maybe add a "compatibility" option. However, I rather suggest upgrading your installation, at least when TeX Live 2017 is released.

The Option straightquotes was added for version v1.05 released 2014/11/18.
