[8] Request for review: 8016848: javax_security/auth/login tests fail in compact 1 and 2 profiles

[Valerie (Yu-Ching) Peng]

Sounds like Xuelie is referring to the general model between the XXX and 
XXXSpi classes, i.e. XXX is the public class which encapsulate XXXSpi 
(the underlying engine class that service providers implement). For 
example, javax.crypto.Cipher and javax.crypto.CipherSpi is one example. 
But I recall there are some classes which do not completely follow the 
model such as java.security.MessageDigest.
