> HttpAsyncService.exception(...) should shutdown connection on IOException
> -------------------------------------------------------------------------
>
> Key: HTTPCORE-379
> URL: https://issues.apache.org/jira/browse/HTTPCORE-379
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore NIO
> Affects Versions: 4.3.2
> Reporter: Dmitry Potapov
> Priority: Minor
> Attachments: NHttpServer.java, shutdown-on-IOException.patch
>
>
> Currently, HttpAsyncService.exception(...) closes connection if response is
> already submitted. On TCP RST packet received all futher attempts to write
> into socket will result in IOException, but SelectionKey.readyOps() won't be
> changed. So, if connection output buffer has some unsent data,
> BaseIOReactor.writable() will be called again and again, but no data will be
> written, so reactor thread will stuck.
> I suggest to shutdown connection if IOException occured, this will save from
> infinite calls to BaseIOReactor.writable()
