javaSE.jar 导致异常

Question

在处理一个项目时，我注意到在模拟器中使用旋转选项时，会引发异常：

Exception in thread "AWT-EventQueue-0" java.lang.Error: 
Cannot call invokeAndWait from the event dispatcher thread

我创建了一个没有这个问题的新项目，在比较它们之后，我注意到 javaSE.jar 的大小不同：

第一个项目的javaSE.jar是17883ko，第二个项目的javaSE.jar是17673ko

如果我在第一个项目中替换 jar，异常就会消失。

这是什么原因？

我正在使用带有最新 CodeNameOne 插件的 Netbeans 8.2。

这是堆栈跟踪：

你有一个旧罐子。如果遇到问题，您需要更新客户端库。右键项目，选择：Codename One -> Codename One Settings -> Basic -> Update Client Libs。

当报告问题时，始终报告最新的最新版本。
