Java 运行我的应用程序时出现NoSuchAlgorithmException

我已将JDK从1.6更改为JDK1.8.0_121。但是，当我运行cmd作业时，会出现以下异常

WRAPPED EXCEPTION (Depth 1): java.security.NoSuchAlgorithmException: algorithm RSA/ECB/PKCS1Padding is not available from provider Cryptix

我添加了无限强度Java（TM）加密 Java（TM）平台的扩展（JCE）策略文件，标准 版本（Java SE）运行时环境8到jre/lib/security，但仍然存在相同的异常。
