• 參考網頁

　　搜索了一下，說JDK242正常，252出現的問題。

java - Apple AWT Internal Exception: NSWindow drag regions should only be invalidated on the Main Thread - Stack Overflow

　　吾試了一下，使用官方發(fā)布的JDK202確實是可以的。由錯誤變成了警告。下載鏈接：

• ?原因分析

　　對比老新版本的JDK輸出，由Warning變成了Error。說明JDK本身沒有變化，變化的是Xcode版本（新版本要求必須在主線程進行某些操作）。而其他軟件沒有及時跟進，于是出錯了。
