android studio + jdk7 的bug

最近换了 mac book pro，重新安装 jdk 时默认选择了 jdk 8，结果下载 android studio 2.1.2 后没法启动。显示如下 crash 信息：

java.lang.reflect.InvocationTargetException

后来 google 之，找到一个简单的解决方案（rpath设置不全的原因）：

cd /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/lib/
sudo cp -rf libosxapp.dylib lwawt/
