java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.JceSecurityManager

Make sure the following files on executing JRE is NOT corrupted/modified/deleted.

• jre\lib\security\local_policy.jar

• jre\lib\security\US_export_policy.jar

I had a similar issue which was caused by manually copying these two files from different java version. Resolved after replacing with original files.

解決方法是確保以上jar包沒改變過，比如是替換整個jar包，替換jar包裏面的class。
