> Key: HTTPCORE-231
> URL: https://issues.apache.org/jira/browse/HTTPCORE-231
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore NIO
> Affects Versions: 4.1-beta2
> Reporter: Yongxing Wang
> Fix For: 4.1
>
> Attachments: HTTPCORE-231.patch
>
>
> 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.
