Access restriction: The constructor SunJCE() is not accessible due to restriction on required library... 
     在研究java密碼編譯演算法時出現了以下編譯錯誤： Access restriction: The constructor SunJCE() is not accessible due to restriction on required library 
sunjce_provider.jar 由於必須的庫限限制訪問，SunJCE() 建構函式不可訪問。 

       在網上搜了一下，解決辦法是修改編譯選項，方法如下：Window -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference
(access rules) -> Warnings，或者在項目上修改編譯選項。
