idea 启动Class JavaLaunchHelper is implemented in both 。。。，

Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/bin/java (0x10eb364c0) and /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10f6714e0). One of the two will be used. Which one is undefined.

解决办法：

点击IntelliJ IDEA最上面菜单的”Help”下的“Edit Custom Properties”，没有这个properties文件的话，IntelliJ IDEA会提示创建，在文件中加上
idea.no.launcher=true
重启IntelliJ IDEA
