> We are using HTTP NIO in our production env and we recently found out that we
> can not download any file with size greater than Integer.MAX_VALUE. The amount
> of data we can download is always "actual_file_size - Integer.MAX_VALUE" in that
> case.
> Further looking into the code, I have found that the implementation of
> LengthDelimitedDecoder there is a line of code:
> int lenRemaining = (int) (this.contentLength - this.len);
> I believe the cast to int is causing the problem when contentLength is over 4G.
> Once I changed lenRemaining to long and make other necessary changes to let it
> compile, it works great.
