While uploading big files (> 2.1 GB) request ends with integer overflow that happens exactly here:

https://github.com/spring-projects/spring-framework/blob/master/spring-web/src/main/java/org/springframework/http/codec/multipart/SynchronossPartHttpMessageReader.java#L141

Content-Length being Long is converted to int.

This is converted to an int because that's what's expected by the MultiplartContext of the underlying multipart library. I've created synchronoss/nio-multipart#10 but in the mean time I can apply a workaround to to avoid the IllegalArgumentException. From what I can tell the contentLength property of MultipartContext is not used anywhere.

Hello, I've created pull request to the underlying library. 

synchronoss/nio-multipart#11

If they will accept that. You could change it to long directly
