<Swing Dev> Swing and imageio-related types that are candidates to be FunctionalInterfaces in JDK 8

[Sergey Bylokhov]

Hi, Joe.
Probably the question is not related but why this annotation is named as 
@FunctionalInterface? Why it wasn't named as @Functional? Or in the 
future we could get something like @FunctionalClass?
@Override isn't @OverrideMethod.
