Oleg Kalnichevski commented on HTTPCORE-651:
--------------------------------------------
[~henry.smith] I see nothing in the stack trace that would suggest a server
side defect of any kind. It appears the message exchange failed due to a
connectivity problem, likely on the client side. Connectivity problems are
normal and can happen. The client should be prepared to handle those and re-try
the request if required.
Do you have the corresponding client side log?

> javax.net.ssl.SSLException: SSL peer shut down incorrectly
> ----------------------------------------------------------
>
> Key: HTTPCORE-651
> URL: https://issues.apache.org/jira/browse/HTTPCORE-651
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore
> Environment: httpcore 4.5, ubuntu 16.04, open jdk 1.8
> Reporter: Henry Smith
> Priority: Major
>
> sometimes the httpcore library generates an exception
>
> javax.net.ssl.SSLException: SSL peer shut down incorrectly
>
> during a file upload (when reading data from the input stream)
> HttpEntity entity = ((HttpEntityEnclosingRequest)httpRequest).getEntity();
> InputStream is = entity.getContent();
> int data;
> while(data!=-1){
> data = is.readData();
> }
> httpRequest is instance of org.apache.http.HttpRequest HttpRequest
>
> Httpcore is used as a web server/file server, based on this example
> [https://hc.apache.org/httpcomponents-core-4.4.x/httpcore/examples/org/apache/http/examples/HttpFileServer.java]
> And users upload their files via their web browsers (using Ajax)
> var file=document.getElementById("file").files[0];
> var data = new FormData();
> data.append("file", file);
> xmlhttp.open("Post","upload",true);
> xmlhttp.send(data);
>
> I have not managed to replicate the issue, in all our tests the httpcore
> works fine both in the development as well as production environment,
> however, in the production environment, this exception is sometimes
> experienced causing termination of the file upload (e.g. in the middle of the
> file upload i.e. half of the file already uploaded).
> By reading posts on different forums, this exception appear to be related
> when plain text sockets are wrapped in as ssl context, and when the server
> terminates the socket (i.e. it does not terminate the socket as the SSL
> socket but as plain text socket). Not sure whether that's applicable in this
> case, because, in majority of case, files are uploaded successfully.
> Additional observation, typically this issue happens to users located in
> developing countries, suggesting maybe some underlying network connectivity
> issues. It rarely happens to users located in developed countries. Any help
> will be much appreciated. Thanks.
