Description

A stack trace of mine shows that call of IOException.closeQuietly() forwarded an NPE up from the JetS3t library's close() method. We may want to have the various CloseQuietly() method intercept and log such things too, on the assumption that the goal of those close operations is to downgrade all close-time exceptions into log events.

If people agree that's what we want, I'll do the patch & test
