>
> When prefetch on open is specified, there is a deadlocking case
> where if the prefetch is cancelled, the PrefetchExecutor interrupts
> the threads if necessary, when that happens in FileIOEngine, it
> causes an ClosedByInterruptException which is a subclass of
> ClosedChannelException. If we retry all ClosedChannelExceptions,
> this will lock as this access is expected to be interrupted.
> This change removes calling refreshFileConnections for
> ClosedByInterruptExceptions.
