Eric Norman commented on FILEUPLOAD-293:
----------------------------------------
[[email protected]] I understand, but I would argue that unnecessarily
changing the behavior of the previous release is in fact a serious problem that
would warrant releasing an official fix. Downstream consumers expect to be
able to plug in the new release without having to rewrite their existing code
and do this regression dance.

> Key: FILEUPLOAD-293
> URL: https://issues.apache.org/jira/browse/FILEUPLOAD-293
> Project: Commons FileUpload
> Issue Type: Bug
> Affects Versions: 1.4
> Reporter: Mladen Girazovski
> Assignee: Jochen Wiedmann
> Priority: Major
> Fix For: Nightly Builds
>
>
> Since 1.4, where FILEUPLOAD-248 was shipped, passing an existing file to
> DiskFileItem.write will cause an FileExistsException with the message
> "Destination FILE already exist", this prevents us from upgrading to 1.4 from
> 1.3.3.
