------------------------------------------
[~olegk] Yes you are right, I was looking at it from the wrong side. I will
revert this change from my client and check if the server will still send the
bigger frames. If yes, I will notify the server's owner to report a bug to a
software he is using.
I am sorry for the confusion, it's good to know where's the real issue now!
Best Regards,
Lubos
> AbstractH2StreamMultiplexer: FrameOutputBuffer: Frame size exceeds maximum
> --------------------------------------------------------------------------

> Key: HTTPCORE-707
> URL: https://issues.apache.org/jira/browse/HTTPCORE-707
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore NIO
> Affects Versions: 5.2-alpha1
> Reporter: Lubos Husivarga
> Priority: Major
> Fix For: 5.1.4, 5.2-beta1
>
> Attachments: context_wire_log.txt, http2_flow_frame.txt
>
>
> AbstractH2StreamMultiplexer initializes outputBuffer with frame size from
> local config:
> _this.outputBuffer = new FrameOutputBuffer(this.outputMetrics,
> this.{*}localConfig{*}.getMaxFrameSize());_
>
> Data are streamed using streamData(...) method which checks maxPayloadSize
> against remote config:
> _final int maxPayloadSize = Math.min(capacity,
> {*}remoteConfig{*}.getMaxFrameSize());_
>
> Issue: When remote config has greater max frame size than local config and
> the payload is also greater than local max frame size, the FrameOutputBuffer
> throws "Frame size exceeds maximum" error, since it compares the payload size
> against local frame size as it was initialized with it, not remote frame size.
>
> My suggestion: AbstractH2StreamMultiplexer.{*}applyRemoteSettings{*}(...)
> should update the outputBuffer's max frame size based on remote config.
>
> I will appreciate your help, as it is really annoying issue depending on
> remote site config and payload size, so it may be spotted randomly.
