> [Tailer] InterruptedException while the thead is sleeping is silently ignored
> -----------------------------------------------------------------------------
>
> Key: IO-357
> URL: https://issues.apache.org/jira/browse/IO-357
> Project: Commons IO
> Issue Type: Bug
> Components: Streams/Writers
> Affects Versions: 2.4
> Reporter: Morten Hattesen
> Fix For: 2.5
>
>
> The implementation of org.apache.commons.io.input.Tailer silently ignores
> interruptions while sleeping (in two places).
> Source snippet:
> {code}
> 360 try {
> 361 Thread.sleep(delayMillis);
> 362 } catch (InterruptedException e) {
> 363 }
> ...
> 425 try {
> 426 Thread.sleep(delayMillis);
> 427 } catch (InterruptedException e) {
> 428 }
> {code}
> This is an inappropriate behavior, since it prevents controlled shutdown by a
> container.
> This may be rectified in one of these ways:
> # Declare the method as "throws InterruptedException" and re-throw the
> InterruptedException, after possibly performing come cleanup, or removing the
> catch clause entirely. This will ensure that a thread interruption (possibly
> caused by the forced shutdown by a container) will cause processing to stop,
> and shutdown to proceed. Problem: Requires backwards incompatible change to
> method signature.
> # Treat an interrupt as an alternate way of signalling the Tailer to stop, by
> calling {{stop()}} in the catch clause.
> # Reassert the interrupted state of the thread by calling
> {{Thread.currentThread.interrupt()}} to be able to detect the interruption at
> a later stage.
