Jdk1.7.0_79.jdk和AppEngine：类JavaLaunchHelper在两者中实现

Question

我有一个简单的Google App Engine项目。当我尝试在localhost上作为Web应用程序运行时，我得到了这个：

objc[49307]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.
Usage: <dev-appserver> [options] <app directory>

配置：针对Ecplise 4.4的MAC OSX El Capitan + Eclipse 4.4.2 + Google插件

我认为该问题已由Oracle修复，版本1.7.0_45上存在同样的问题：

• Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined
• objc[10012]: Class JavaLaunchHelper is implemented in both ... libinstrument.dylib. One of the two will be used. Which one is undefined）

所以我无法使用Google Plugin For Eclipse本地测试我的应用程序..出了什么问题？
