A simple thing to consider is whether there are several such things that you 
will do, or just the one.  For 3 or more things, I'd suggest a 
ThreadPoolExecutor.  If the tasks are done with time based triggering, a 
ScheduledThreadPoolExecutor is convenient.  If the events are triggered by some 
event, such as service discovery, or lease/transaction expiration based etc, 
then use a ThreadPoolExecutor to dispatch them as needed.

If you just have one or two things to do, the thread pool won't add much value., 
it will just be another live object to deal with the lifecycle thereof.  But I 
usually use a Runnable/Callable based design from the start to allow an easy 
switch over.

Future's are particularly nice for things that need to be done in the 
background, but which multiple threads of execution need the results of.  The 
work can be dispatched in a synchronized block, and then everyone can block on 
Future.get().
