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}
Caused by: java.io.EOFException: Unexpected EOF read on the socket
