Question

我刚刚将Eclipse中的Codenameone项目移植到新的MacBook上。当我启动模拟器时，在eclipse的控制台中显示错误。因此，新安装的皮肤将不会被存储，并且会在下次启动模拟器时消失。

这是错误的堆栈跟踪。你有什么想法，原因是什么？也许存在一些在新款MacBook上无法匹配的模式？

这是Java SE首选项API的一个例外，请参阅此Where are Java preferences stored on Mac OS X?

检查Mac OS上的用户是否具有访问该文件夹的权限，以及Java SE进程是否也具有此类权限。请注意，我们使用的用户节点应该始终有效并且永远不会存储到系统节点。
