Miguel Munoz commented on IO-813:
---------------------------------
[~elharo] Can you tell us under what conditions lastModified might throw an
exception inconsistently? Would this be because the file gets modified in
between calls? Or is this from something else? The only exception declared on
{{File.lastModified()}} is SecurityException, and I don't see why that would be
inconsistent.
> 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.
