>          Issue Type: Bug
>    Affects Versions: 1.2.2
>         Environment: Tomcat 7, java 1.6, osx

> When performing multi-part file upload using chunked data, if a multi-part section includes separate data chunks it is not correctly parsed and causes FileUpload to throw "MalformedStreamException: Stream ended unexpectedly"
> Having chunked content within a multi-part boundaries is as far as I am aware valid.
> The reason my client has chunked content within file boundaries is that an audio file is uploaded as it is being recorded.
> Example with chunked data within file boundary
> POST /UploadServlet HTTP/1.1
