             Summary: Getting org.apache.http.ConnectionClosedException after httpcore-nio version upgrade
                 Key: HTTPCORE-718
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-718
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore NIO
    Affects Versions: 4.4.15
         Environment: Java version: 11.0.15.1
OS: macOS Monterey (Version 12.12.1) 
            Reporter: Sajinie Kavindya
         Attachments: HttpNIOTestClient-1.zip

We recently migrated to httpcore-nio 4.4.15 and we have been encountering some issues when connecting to an HTTPS Backend that sends chunked responses. The backend behaves in such a manner that when it sends the response, it immediately closes the connection after completion. 

We have attached a reproducer to this ticket and the behavior is as below.

When httpcore-nio 4.4.15 is used, the client gets the error:
{code:java}
org.apache.http.ConnectionClosedException: Connection closed unexpectedly{code}
But, when httpcore-nio 4.4.5 is used, the client receives the complete response, which was sent from the backend.

We further checked on the following versions and the observations are as below. 
 * httpcore-nio 4.4.10 - receives the complete response
 * httpcore-nio 4.4.11 - receives org.apache.http.ConnectionClosedException

In order to replicate the issue, we did a few changes to the consumeContent(final ContentDecoder decoder) method inside the SimpleInputBuffer class. You may find the changes in the attached source code.

In order to test the behavior, please run the Main class: “{*}TestChunkedBackend{*}”.

Tested environment:
 * Java version: 11.0.15.1
 * OS: macOS Monterey (Version 12.12.1)

Thanks & Regards,
Sajinie
