> If a non-I/O exception occurs while the DeletionService is executing a deletion task
then it will be silently ignored.  The exception bubbles up to the thread workers of the ScheduledThreadPoolExecutor
which simply attaches the throwable to the Future that was returned when the task was scheduled.
 However the thread pool is used as a fire-and-forget pool, so nothing ever looks at the Future
and therefore the exception is never logged.
