Gary D. Gregory commented on IO-813:
------------------------------------
Here is an unrelated example (in the abstract for IO) of why throwing an
exception is good:
https://lists.apache.org/thread/scvg6r3jxm1prh4gyvv03x6lx23zobs6
> LastModifiedFileComparator should not throw exceptions, period
> --------------------------------------------------------------
>
> Key: IO-813
> URL: https://issues.apache.org/jira/browse/IO-813
> Project: Commons IO
> Issue Type: Bug
> Reporter: Elliotte Rusty Harold
> Priority: Major
>
> LastModifiedFileComparator is likely broken by design since it can
> unexpectedly throw UncheckedIOException. This violates the contract of
> Comparable.compareTo which is not documented to throw that exception.
> I analyzed almost this exact case in detail here:
> https://medium.com/@elharo/when-you-cant-throw-an-exception-b9f9b0db9ba4
> I'm not sure how to fix this now, but I'm, tempted to simply deprecate this
> entire class.
