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

[Phil Race]

Joe,

Note that Swing is a single threaded API. You can't update the UI from
any thread other than the EDT.
Where any automatic usage of processing in parallel from additional threads
is performed by the lambda implementation it will violate that requirement.
So you should be circumspect in tagging Swing classes.
