Looking over the comments in the com/sun/security/sasl/digest/PrivacyRc4.java
class, it says:

 * @ignore RC4 ciphers not in std JDK; run this by hand after installing RC4 cipher.

This was added to JDK's reg suite area by rosanna back in 03, I'm assuming
before tiger had an RC4 cipher (ARCFOUR).

Should this test be enabled now?

As it is, it's failing when running by hand.
