> Key: HTTPCORE-372
> URL: https://issues.apache.org/jira/browse/HTTPCORE-372
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore, HttpCore NIO
> Affects Versions: 4.4-alpha1
> Reporter: Dmitry Potapov

> I've found that both these classes treats chunked streams without closing chunk as complete streams without any errors. This contradicts RFC2616 ยง3.6.1
> Consider the following scenario:
> 1. HttpClient sends request to Server
> 2. Server accepts request and send response headers with Transfer-Encoding: chunked
> 3. Server sends first chunk completely and dies with segfault before sending the next chunk
> 4. HttpClient receives response headers and creates ChunkedInputStream
> 5. ChunkedInputStream reads this first chunk and encounters eof
> Expected result:
> IOException thrown indicating incomplete response
> Actual result:
> No exception is thrown, -1 is returned on the next read and nobody knows that response is incomplete.
