Answer 1

把这个函数调用屏蔽掉是没有问题，不过用myeclipse 设计图形界面会自动增加上这个函数。

Answer 2

java.awt.AWTPermission   
只有下面几个权限限制：
 *   <td>accessClipboard</td>
 *   <td>accessEventQueue</td>
 *   <td>listenToAllAWTEvents</td>
 *   <td>showWindowWithoutWarningBanner</td>
 *   <td>readDisplayPixels</td>
 *   <td>createRobot</td>
 *   <td>fullScreenExclusive</td>
哥们用的JDK版本是多少呢？
