Use this program to reproduce the failure (works fine with standard J2SDK):

import java.security.*;
import javax.crypto.*;
import javax.crypto.spec.*;

public class JCE {
        public static void main(String[] args) throws Exception {
                SecretKeyFactory keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES", "SunJCE");
        }
}
