在使用eclipse时对象后使用点操作符时总是会弹出错误，很是烦人

An internal error occurred during: "Computing additional info".Could not initialize class javax.crypto.JceSecurityManager

解决方式：

1. 找到JDK安装目录下的src.zip文件；2. 打开eclipse: Window菜单->Preference->Java->Installed JREs；3. 在列表中选择你eclipse正在使用的JRE，然后Edit；4. 选择rt.jar，然后点击"Source Attachment"按钮，弹出对话框后选择"External File"，然后把你的JDK安装目录下的src.zip文件与rt.jar关联上。
