Interestingly, there is `nullptr` usage in 11u; in the AIX port, some Windows code and [JDK-8282588](https://bugs.openjdk.org/browse/JDK-8282588) exists to allow C++11 for HarfBuzz which uses it. So you can actually only compile the code without C++11 on some platforms and it needs `--with-harfbuzz=system`
