review request for 7008728: diamond conversion of basic security, permission, authentication code

[Stuart Marks]

The third batch of diamond conversions in the security area. This one's for 
Sean. Can you review this? Webrev is here:

In particular, take a look at

src/share/classes/javax/security/auth/Subject.java

It looks like the converter might have missed a diamond opportunity at line 
157. Hmmm. Let me know what you think.

Thanks!
