> JobTracker.close() prints a stack trace for an interrupted exception even
> though it was the method that interrupted the thread that threw the
> exception. For example:
> {code}
> this.expireTrackers.stopTracker();
> try {
> this.expireTrackersThread.interrupt();
> this.expireTrackersThread.join();
> } catch (InterruptedException ex) {
> ex.printStackTrace();
> }
> {code}
> Well of course it is going to catch an InterruptedException after it just
> interrupted the thread!
> This is *not* an error and should *not* be dumped to the logs!
> In other circumstances, catching InterruptedException is entirely
> appropriate. Just not in close where you've told the thread to shutdown and
> then interrupted it to ensure it does!
