[jira] [Created] (HTTPCORE-651) javax.net.ssl.SSLException: SSL peer shut down incorrectly

Henry Smith created HTTPCORE-651:
------------------------------------

             Summary: 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


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.
