报错

报错信息如下:

Access restriction: The type RepaintArea is not accessible due to restriction on required library D:\MYEclipseWork\binary\com.sun.java.jdk7.win32.x86_64_1.7.0.u45\jre\lib\rt.jar

选中该工程右键--->Build Path-->Configure Build Path把工程中的JRE System Library去掉，在重新添加myeclipse/eclipse中配置的JRE System Library，刷新工程即可。
