Mac 版本IDEA "Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachie，

objc[1111]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/bin/java (0x10d6c34c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10d79f4e0). One of the two will be used. Which one is undefined.

Stack Overflow说这是Mac上面Java的一个老Bug了，会在那些使用了Java Agent的IDE上运行应用时触发，但这个Error对程序是无影响的，可以无视。在Java 9和Java 1.8.152版本里已经修复了。
