Motivation Currently when future tasks are scheduled via schedule(Runnable, ...) methods, the supplied Runnable is wrapped in a newly allocated Callable adapter prior to being wrapped in a ScheduledFutureTask. This can be avoided which saves an object allocation per scheduled task. Modifications Change the Callable task field of ScheduledFutureTask to be of type Object so that it can hold/run Runnables directly in addition to Callables. An "adapter" is still used in the case a Runnable is scheduled with an explicit constant non-null completion value, assumed to be rare. Result Less garbage |
