Description

FileItem.write throws FileExistsException (org.apache.commons.io.FileExistsException) when we try to re-upload (or overwrite) a file.

What works in v1.3.3:

1. User tries to upload a file user1.png
2. It is stored in the server at c:\data\avatar\user1.png using FileItem.write
3. User tries to upload the same file user1.png
4. FileItem.write replaces the file c:\data\avatar\user1.png in the server with the new file

In v1.4:

Step 4 fails with an exception - org.apache.commons.io.FileExistsException

 

Stack Trace:

org.apache.commons.io.FileExistsException: Destination 'c:\data\avatar\user1.png' already exists
  at org.apache.commons.io.FileUtils.moveFile(FileUtils.java:3001)
  at org.apache.commons.fileupload.disk.DiskFileItem.write(DiskFileItem.java:405)
