Description

Hi,

This report is spawn from a bug found in commons-fileupload:1.4 and up.

 

https://issues.apache.org/jira/browse/FILEUPLOAD-338

 

The code at this line:

https://github.com/apache/commons-io/blob/f22a4227401855ecbfdf8184bbe37275c3aeb5c3/src/main/java/org/apache/commons/io/FileUtils.java#L2392

 

can cause IOException when the .tmp file is deleted during the writing the upload file to disk.

We found that the java process holding on to the open handler of the .tmp file (during the read for writing to the destination file); thus the delete() operation fails and the IOException is thrown.

 

This problem only happens on Windows.

 

Thanks,
