["Fernando Hartmann (Jira)" <ji...@apache.org>]

Fernando Hartmann created FILEUPLOAD-307:
--------------------------------------------

             Summary: Request InputStream created in FileItemIteratorImpl can be left open
                 Key: FILEUPLOAD-307
                 URL: https://issues.apache.org/jira/browse/FILEUPLOAD-307
             Project: Commons FileUpload
          Issue Type: Bug
    Affects Versions: 1.4
            Reporter: Fernando Hartmann


Some exceptions in FileUploadBase.parseRequest you can leave Request InputStream open, leading to a memory leak, because FileItemIteratorImpl InputStream is not closed.

In my case the following Exception generates the problem.

 
{code:java}
