Description

When doing a file upload with a file size exceeding 2GB:

curl -F "my_file=@a_very_large_file" --header "Content-Type: multipart/related; type=application/atom+xml" http://...

the following server code snippet:

<%
org.apache.sling.api.request.RequestParameter fileParam = slingRequest.getRequestParameter("my_file");
%>

will report a "null" fileParam. Reason for this is a limitation in commons-fileupload-1.1.1 which is embedded in sling-engine: the servlet container will report a content length of -1 (as the size is not representable in an integer) and FileUploadBase.parseRequest then throws an "UnknownSizeException". This was fixed in commons-fileupload-1.2.1.
