---------------------------------------

             Summary: AbstractCharDataConsumer throws 
java.nio.charset.MalformedInputException for an URI that SimpleResponseConsumer 
can handle
                 Key: HTTPCLIENT-2300
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2300
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient (async)
    Affects Versions: 5.2.1
         Environment: openjdk version "17.0.8.1" 2023-08-24
OpenJDK Runtime Environment Temurin-17.0.8.1+1 (build 17.0.8.1+1)
OpenJDK 64-Bit Server VM Temurin-17.0.8.1+1 (build 17.0.8.1+1, mixed mode, 
sharing)
            Reporter: Michael Lee
         Attachments: sample.zip

HttpAsyncClient is able to retrieve the response body of 
[https://www.videolan.org/vlc/] using a SimpleResponseConsumer but not a 
trivial subclass of AbstractCharResponseConsumer. Using the latter, 
AbstractCharDataConsumer.consume throws an exception. Excerpt:

 

{{java.nio.charset.MalformedInputException: Input length = 1}}
{{    at 
java.base/java.nio.charset.CoderResult.throwException(CoderResult.java:274)}}
{{    at 
org.apache.hc.core5.http.nio.entity.AbstractCharDataConsumer.checkResult(AbstractCharDataConsumer.java:103)}}
{{    at 
org.apache.hc.core5.http.nio.entity.AbstractCharDataConsumer.consume(AbstractCharDataConsumer.java:156)}}
{{    at 
org.apache.hc.client5.http.impl.async.HttpAsyncMainClientExec$1.consume(HttpAsyncMainClientExec.java:243)}}
{{    at 
org.apache.hc.core5.http2.impl.nio.ClientH2StreamHandler.consumeData(ClientH2StreamHandler.java:235)}}

 

On the other hand, the same code works fine for other URLs such as 
[https://httpbin.org/]

 

Attached HttpAsyncClientTests.java illustrates the issue. The method testSimple 
using SimpleResponseConsumer works fine, but the method testStreaming using a 
trivial subclass of AbstractCharResponseConsumer does not.
