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