[xwiki-users] java.security.NoSuchAlgorithmException: Cannot find any provider supporting DES/ECB/PKCS5Padding

I've deployed Xwiki enterprise 2.7 on my Glassfish 2.1.1 server with MySQL as the back-end. I can create a user, but when I try to log in to that user, I am rewarded with the stack dump shown below. It's trying to find a provider of DES/ECB/PKCS5Padding. After about 30 minutes on Google and on Java.sun.com, I don't seem to be able to find where I can get this provider. Could some kind soul please give me some hints on where to look to download this? Thanks.
