-----------------------------------------
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)
