在macos yosemite上编译openjdk9

在 wiki 上查看不同系统的支持状况

1. 安装xquartz
2. 安装freetype: brew install freetype
3. 要有oracle jdk8以上， 如果configure时候找不到， 需要
4. 跟官网介绍，我编译的是dev的 fastdebug版本

   hg clone http://hg.openjdk.java.net/jdk9/jdk9 jdk9
   cd ./jdk9
   ./get_source.sh (This will take sometime to download the sources so be patient. May be few hours sometimes)
   ./configure –enable-debug –with-target-bits=64

测试xcode7下也可以编译成功
