Security-related types that are candidates to be FunctionalInterfaces in JDK 8

[Joe Darcy]

Hello,

As part of Project Lambda, a FunctionalInterface annotation type was 
added to the platform to mark interfaces that are intended to be used in 
lambda expressions.  I've sent out a code review request to add this 
annotation to types in the core-libs area [1].

To assist the security team in adding analogous annotations to your 
types, the list of candidate types in for security-related classes in 
java.* and javax.* is given below.  I recommend sub-tasks of JDK-8005297 
"Add FunctionalInterface support to the platform" be used to track the 
work of adding @FunctionalInterface annotations to security types.

Thanks,

-Joe
