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 swing team in adding analogous annotations to your
types, the list of candidate types in for swing and imageio-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
swing types.
Thanks,
-Joe
